"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
