Question

what is the surface area of the rectangular prism please explain i failed my last session and im just trying to get through this without any mistakes​

Answer 1

B. 250 ft²

Explanation:

We have two squares S × S and four rectangles S × L.

S = 5 ft and L = 10 ft.

The area of a square:

`A_s=(5)(5)=25\ ft^2`

The area of a rectangle:

`A_r=(5)(10)=50\ ft^2`

The Surface Area:

`S.A.=2A_s+4A_r`

Substitute:

`S.A.=2(25)+4(50)=50+200=250\ ft^2`
