Answer 2

b.

2528 sq. ft

Explanation:

Surface area of rectangular prism:

A rectangular prism has length l, width w and height h. It's surface area is given by:

`S = 2(lw + lh + wh)`

In this question:

We have that
`l = 34, w = 21, h = 10`

So the surface area is

`S = 2(lw + lh + wh) = 2*(34*21 + 34*10 + 21*10) = 2528`

2528 square feet, option b.
