find the surface area of the complex figure.

a) 300 feet squared

b) 225 feet squared

c) 550 feet squared

d) 525 feet squared

Optión C.

Step-by-step explanation:

1. The surface area of the complex figure is the sum of the surface area of 5 of the faces of both cubes and the surface area of 5 of the faces of the rectangular prism.

2. The formula to calculate the surface area of one of the faces of a cube is:

where L is the length or width of the face.

We must calculate the area of 5 of the faces for both cubes, since the area of the lower face is not part of the figure.

3. The formula for calculating the surface area of a rectangular prism is

Where

L = length

h = height

w = width

In this case we should not calculate the area of the entire upper face of the rectangular prism, but only the area of the square whose side is 5 ft that is in the middle of the figure. Then we subtract from the formula and we have left:

4. Therefore, the surface area of the complex figure is:

The correct answer is option C.
