Question

A pond is created by digging a rectangular prism. The hole is 3 yards wide, 4 yards long, and 2 yards deep. The sides and bottom of the pond are lined with a protective plastic. How many square yards of the plastic are used?

Answer 1

Answer: (C)

Step-by-step explanation: 40 square yards.

Answer 2

Find the area of the 5 sides (not 6 because the top is open).
The area is made up of a load of rectangles. 2 of each rectangle are present except the top and bottom.
(4 x 2 x 2) + (3 x 2 x 2) + (3 x 4) = 40yd²
