Answer:

652 ft²

Explanation:

Look at the picture.

It's a net of right rectangular prism.

We have three pairs of rectangles:

7ft × 8ft

7ft × 18ft

8ft × 18ft

The formula of an area of a rectangle l × w:

A = lw

Calculate the areas:

A= (7)(8) = 56 ft²

A = (7)(18) = 126 ft²

A = (8)(18) = 144 ft²

The Surface Area :

S.A. = 2A + 2A+ 2A

Substitute:

S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
