Answer :
Answer:
b.
2528 sq. ft
Step-by-step explanation:
Surface area of rectangular prism:
A rectangular prism has length l, width w and height h. It's surface area is given by:
[tex]S = 2(lw + lh + wh)[/tex]
In this question:
We have that [tex]l = 34, w = 21, h = 10[/tex]
So the surface area is
[tex]S = 2(lw + lh + wh) = 2*(34*21 + 34*10 + 21*10) = 2528[/tex]
2528 square feet, option b.
