"How tall is the refrigerator if it has a square base with sides that are 3 feet long and a capacity of 40.5 cubic feet?"

:

The volume in cubic ft; Length * Width * Height = 40.5

The base is square therefore the length and width = 3, we will find h

3 * 3 * h = 40.5

9h = 40.5

divide both sides by 9

h = 40.5/9

h = 4.5 ft tall

Check this; 3 * 3 * 4.5 = 40.5
