# Lesson 13

How Much Will Fit?

### Problem 1

- Sketch a cube and label its side length as 4 cm (this will be Cube A).
- Sketch a cube with sides that are twice as long as Cube A and label its side length (this will be Cube B).
- Find the volumes of Cube A and Cube B.

### Problem 3

The graph represents the volume of a cylinder with a height equal to its radius.

- When the diameter is 2 cm, what is the radius of the cylinder?
- Express the volume of a cube of side length \(s\) as an equation.
- Make a table for volume of the cube at \(s = \) 0 cm, \(s = \) 1 cm, \(s = \) 2 cm, and \(s = \) 3 cm.
- Which volume is greater: the volume of the cube when \(s =\) 3 cm, or the volume of the cylinder when its diameter is 3 cm?
