Volume - High School Math

A sand box is in the shape of a cube measuring 2 feet on each side. If the sand box weighs 12 pounds per cubic foot, find the total weight of the sand box in pounds?

Answer: 96 pounds

Explanation:
In order to find the total weight in pounds we must first find the volume of the cube.
The formula for volume is as follows:

V = lwh
V = 2 x 2 x 2 = 8 cubic feet

Since there is 12 pounds per each cubic foot, we set up the relationship as follows:
Weight = 8 cubic feet x 12 pounds/cubic feet = 96 pounds
Note that the units for cubic feet cancel out and we are left with only the units for pounds which is what the problems is asking for.
