Question

What is the area of this composite solid?

Answer 1

Answer:

162 m²

Step-by-step explanation:

To find the area of this composite solid, we need to find the area of each surface and sum them up.

Formula for finding area is length x width.

Area of each surface:

3 * 2 = 6

9 * 2 = 18

5 * 2 = 10

2 * 2 = 4

8 * 2 = 16

(11-2) * 3 = 27

Considering the fact that each surface appeared twice in the figure, the area of the surface will be calculated as:

(6 + 18 + 10 + 4 + 16 + 27) * 2

= 81 * 2

= 162 m²
