Question

Find the lateral area and the total area of the prism.

27 sq. ft.
36 sq. ft.
54 sq. ft.

Answer 1

54 sq. ft.

Explanation:

LA=ph or in other words Lateral Area= base perimeter * height

The perimeter of the base is 9 because 3+3+3=9.

The height is 6. So 6 * 9 = 54

Answer 2

we have that

1) the lateral area----------------> L=P*h
P=(3+3+3) h=6
L=(3+3+3)*6=54 in²

the answer part 1) is the lateral area is 54 in²

2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2] P*h=54

S=2*[3*3/2]+54=63 in²

the answer part 2) is the total area is 63 in²
