Question

Find the lateral area of each prism. Round to the nearest tenth if necessary.

a. 64 units2
b. 256 units2
c. 320 units2
d. 384 units2

Answer 1

Option b. 256 units2

Explanation:

we know that

The lateral area of the prism is equal to

`LA=PH`

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base

The base is a square

so

`P=4(8)=32\ units`

we have

`H=8\ units`

substitute in the formula

`LA=(32)(8)=256\ units^(2)`
