Question

What is the lateral surface are of this triangular prism?

Answer 1

Answer:

96 in²

Step-by-step explanation:

Lateral surface area

= 3 rectangles

(4×8) + (3×8) + (5×8)

32 + 24 + 40

96 in²

Answer 2

Answer:

96 inches squared

Step-by-step explanation:

The lateral area of the prism is the part that is not the bases. The bases here are the triangles, which means the lateral area will be the rectangles.

There are 3 rectangles with dimensions:

- 5 in by 8 in

- 4 in by 8 in

- 3 in by 8 in

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. Calculate the areas:

- 5 * 8 = 40

- 4 * 8 = 32

- 3 * 8 = 24

Add these up:

40 + 32 + 24 = 96

The answer is 96 inches squared.
