Question

The side lengths of the base of a triangular prism are 5 meters, 8 meters, and 10 meters. The

height of the prism is 16.5 meters.

Answer 1

379.5 square units

Explanation:

The computation of the lateral surface area of the prism is shown below;

Here we have to use the following formula

= (a + b+ c) ×h

where

a = 5

b = 10

c = 8

And, h = 16.5

SO, the lateral surface area of the prism is

= (5 + 10 + 8) × 16.5

= 23 × 16.5

= 379.5 square units
