What is the surface of the rectangular prism?

A.) 17.5 ft^2
B.) 11.0 ft^2
C.) 12.0 ft^2
D.) 5.5 ft^2

Work Shown:

L = length = 4 ft

W = width = 1.5 ft

H = height = 0.5 ft

S = surface area of rectangular prism

S = 2*(L*W + L*H + W*H)

S = 2*(4*1.5 + 4*0.5 + 1.5*0.5)

S = 17.5

The units for the surface are in square feet. This is because surface area is really the combination of all individual areas of each face.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
