Here you will learn about rectangular prisms, including how to classify and identify rectangular prisms.

Students will first learn about rectangular prisms as a part of geometry in 1 st grade.

A **rectangular prism** is a **three-dimensional shape**, or **3D shape** (polyhedron) with 6 rectangular faces that meet at right angles. They are also known as **cuboids**.

Cubes are a special type of rectangular prism where the length, width and height are all equal.

Examples of a rectangular prism:

Real life examples of rectangular prisms include shoe boxes, books and even the bricks on your house.

The properties of a rectangular prism include faces, edges, vertices (corners), length, width and height.

**Faces**

A **face** of a 3D shape is a flat surface.

Rectangular prisms have a total of \bf{6} ** faces** – all of which are rectangular (or square).

**Edges**

An **edge** of a 3D shape is a straight line between two faces.

Rectangular prisms have \bf{12} **edges**:

**Vertices**

A **vertex** is a point where two or more edges meet.

Rectangular prisms have \bf{8} **vertices**:

**Length, width and height**

A rectangular prism has **three dimensions**: length, width, and height.

The length refers to the measurement from one end of the rectangular prism to the other, the width is the measurement from side to side, and the height of the rectangular prism is the measurement from top to bottom.

**Labeling a rectangular prism**

You can label the vertices (corners) of a rectangular prism to help us identify certain edges or faces.

For example,

Using this labeling you can identify lengths, for example, the length AB :

You can also identify faces, for example, the face ABCD :

How does this relate to 1 st grade math?

**Grade 1: Geometry (1.G.A.2)**Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

DOWNLOAD FREEIn order to identify a rectangular prism, you will:

**Look for the characteristics of a rectangular prism.****State whether or not the shape is a rectangular prism.****If the shape is not a rectangular prism, explain what characteristics are different.**

Look at the image below and determine if it is a rectangular prism or not.

**Look for the characteristics of a rectangular prism.**

2**State whether or not the shape is a rectangular prism.**

This shape is not a rectangular prism, this shape is a pyramid.

3**If the shape is not a rectangular prism, explain what characteristics are different.**

This shape is not a rectangular prism because it has 4 triangular and 1 rectangular face.

Are the side lengths different from each other?

No, all the sides are the same length.

**State whether or not the shape is a rectangular prism.**

The fish tank has 6 rectangular faces.

The fish tank has 8 vertices, or corners.

The fish tank has 12 edges.

Are the side lengths different from each other?

Yes, you can see that the sides on top and bottom are longer than the sides on the left and right.

**State whether or not the shape is a rectangular prism.**

The shape is a rectangular prism.

In order to identify rectangular prisms in a composite shape, you will:

**Count the number of shapes that make up the composite shape.****Identify and count the number of rectangular prisms within the shape.****State the number of rectangular prisms within the composite shape.**

Look at the composite shape and identify all rectangular prisms.

**Count the number of shapes that make up the composite shape.**

The composite shape is made up of 7 shapes.

**Identify and count the number of rectangular prisms within the shape.**

Each of these shapes has 6 regular faces that meet at right angles.

**State the number of rectangular prisms within the composite shape.**

The composite shape has 5 rectangular prisms: 3 cubes and 2 rectangular prisms.

Look at the composite shape and identify all rectangular prisms.

**Count the number of shapes that make up the composite shape.**

The composite shape is made up of 6 shapes.

**Identify and count the number of rectangular prisms within the shape.**

Each of these shapes has 6 regular faces that meet at right angles.

**State the number of rectangular prisms within the composite shape.**

The composite shape has 4 rectangular prisms: 2 cubes and 2 rectangular prisms.

Look at the composite shape and identify all rectangular prisms.

**Count the number of shapes that make up the composite shape.**

The composite shape is made up of 7 shapes.

**Identify and count the number of rectangular prisms within the shape.**

Each of these shapes has 6 regular faces that meet at right angles.

The composite shape has 5 rectangular prisms.

- Allow students the opportunity to explore and manipulate real-life examples of a rectangular prism. Some real-life examples of rectangular prisms are shoeboxes, books, refrigerators, and televisions. These objects have a box-like shape with rectangular sides.

- Provide students with physical rectangular prisms or building blocks to explore and manipulate. This hands-on approach helps them visualize and understand the properties and dimensions of rectangular prisms.

- With upper elementary students, in lue of working with rectangular prisms on worksheets, allow students to measure and compare the length, width, and height of rectangular prisms using rulers or measuring tapes. This helps reinforce the concept of dimensions and encourages critical thinking.

- Provide students with real-world practice problems or puzzles that involve rectangular prisms. For example, ask middle schoolers to calculate the volume or surface area of a rectangular prism or find the dimensions of an object given its properties.

- With students of all ages, draw connections between rectangular prisms and other geometric shapes, such as squares, rectangles, and cubes. Discuss similarities and differences in their properties to reinforce understanding.

**Assuming cubes are not rectangular prisms**

Some definitions of rectangular prisms note that the sides are different lengths, meaning a cube could not be a rectangular prism. However, cubes are a special kind of rectangular prism, and should be considered one.

**Confusing edges and vertices**

An edge is a line segment where two faces meet, while a vertex is a point where edges intersect.

**Confusing rectangles and rectangular prisms**

Rectangles are 2D (they are made up of a length and width and are flat),**and**rectangular prisms are 3D (they are made up of rectangular faces and are not flat).

A rectangular prism has different lengths, widths, and heights, while a cube has all sides of equal length.

No, parallelograms are two-dimensional shapes, whereas rectangular prisms are three-dimensional shapes. **See also:** Parallelogram

Rectangular prisms are not the only type of prism you will encounter in your math career. As you progress through math, you will learn about other prisms including: hexagonal prisms, pentagonal prisms, and square prisms.

To find the volume of the rectangular prism, you multiply the length, width, and height of the prism together. The rectangular prism formula for volume is: \text{Volume} = \text{length} \times \text{width} \times \text{height} cubic units.**See also:** Volume of a rectangular prism

To calculate the surface area of the rectangular prism, you add up the areas of all six faces. The rectangular prism formula is: \text{Surface Area} = 2 \, (length \times width + width \times height + height \times length). **See also:** Surface area of a rectangular prism

To calculate the lateral surface area of a rectangular prism, you need to find the sum of the areas of all the rectangular faces excluding the top and bottom faces. Here’s the formula: \text{Lateral Surface Area} = 2 \times (length \times height + width \times height).

A rectangular prism has six faces, and all of them are rectangles. Opposite faces of a rectangular prism are congruent and parallel to each other. A triangular prism has two triangular bases and three rectangular faces connecting them. The shape of the faces and the arrangement of the angles differ between the two types of prisms.

It is another name for a rectangular prism – they mean the same thing.
