9-56.

Find the volume and surface area of each shape below. Assume that the edge of each cube measures $1$".

1. Each of these objects are three-dimensional and have length, width, and depth.

Volume is the number of $1\text{-inch}$ cubes needed to fill a three dimensional object.

The surface area of an object is the total area of all its surfaces.

1. See part (a).

1. Including the hidden sides, there are $14$ total square sides each with area 1 sq in. There are $3$ cubes so the volume is $3$ in³.
