Suppose you have the same box with a volume of 400

in.

​​ and a height of 5 in. You now also know that the box is 8 in. wide. What is the length of the box?

To find the length of the box, we can use the formula for the volume of a rectangular prism:

Volume = length x width x height

Given:
Volume = 400 in^3
Height = 5 in
Width = 8 in

Substitute the given values into the formula:

400 = length x 8 x 5

Simplify:

400 = 40 length

Now, divide by 40 on both sides to solve for length:

length = 400 / 40
length = 10 in

Therefore, the length of the box is 10 inches.
