Question

What is the surface area of the solid above?

A. 56 cm?
B. 120 cm2
C. 84 cm?
D. 14 cm?

Answer 1

B: 120cm2

Just find the area of all the faces and add them up.

Answer 2

B) 120 cm^2

Explanation:

First we can find the bottom and top.

The width and length are 6, so;

6x6 = bottom, 6x6 = top.

6x6x2 = bottom + top

6x6x2 = 72.

Now we can find the sides.

Height = 2, width = 6.

2x6 = 1 side, 2x6x4 = 4 sides.

2x6x4 = 48

72 + 48 = total surface area

72 + 48 = 120 cm^2, B)
