# Lesson 5 Side Lengths of Rectangular Prisms

• Let’s describe the side lengths of a prism and find the volume.

## Warm-up Notice and Wonder: Prism Print

What do you notice? What do you wonder?

## Activity 1 All About That Base

Here are 3 rectangular prisms.

These rectangles represent bases of the prisms.

1. Match each prism with a rectangle that represents its base. Note: Some prisms may match more than 1 rectangular base.

2. Find the volume of each prism. Explain or show your reasoning.
