Question

Find the lateral area of each prism. Round to the nearest tenth if necessary. Select one: a. 162 units2 b. 186 units2 c. 210 units2 d. 224 units2

Answer 1

a. 162 units²

Explanation:

The lateral area is area of the lateral sides (in other words, the surface area not including the bases).

Here, the lateral sides are three rectangles. So the total lateral area is:

A = (6)(9) + (8)(9) + (4)(9)

A = 162
