Question

What is the surface area of this?

Answer 1

Surface Area = 96

Explanation:

Area of Triangle: Area = 1/2 * Base * Height

• Top Triangle:

Area = 1/2 * 6 * 2 = 6

• Bottom Triangle:

Area = 6

Area of Rectange: Area = Length * Height

• Left Rectangle:

Area = 7 * 3 = 21

• Mid Rectangle

Area = 7 * 6 = 42

• Right Rectangle

Area = 21

Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect

Surface Area = 6 + 6 + 21 + 42 + 21 = 96
