To master this topic, you should understand the volume and surface area formulas for rectangular solids.
For review the Rectangular Solids topic, see here.
Example 1: Volume
The volume of a rectangular solid is 72 ft3.
The length is 6 ft and the height is 3 ft. What is the width?
w =Use the volume formula and plug in what you know.
Then solve for the unknown.We are solving for the width, w.The answer is w = .
Example 2: Surface Area
The surface area of a rectangular solid is 52 cm2.
The lengths of two of the sides are 4 cm and 2 cm.
What is the length of the other side?
length =Use the surface area formula and plug in what you know.
Then solve for the unknown.Assign width = 4 cm and height = 2 cm.The answer is length = .
We are solving for the length, l.
