Question

What is the width of the prism?
2 ft
w
4 ft
Volume = 24 cubic feet

Answer 1

3 ft

Explanation:

(I assumed that this was a rectangular prism based on the dimensions given, but do correct me if I assumed incorrectly.)

The formula for finding the volume of a rectangular prism is:
`V=w*h*l`

In this case, we already know that the volume of the prism is 24, so we can plug 24 in for V:

`24=w*h*l`

We also already know the height and the length because they gave it to us, so we can plug it in as follows:

`24=w*2*4`

Then we can multiply 2 and 4 on the right side:

`24=w*8`

Then, to get the w alone, we can divide by 8 on both sides:

`3=w`

Now that gives us that the width of the rectangular prism is 3ft.
