Question

Find the lateral area and surface area of the prism.

Answer 1

The lateral area of the prism : 180

The surface area of the prism : 1740

Explanation:

LA = Lateral area

P = perimeter

H = Height

• LA = P x H

The perimeter of the would be 12 + 5 + 13 = 30 and the height would be 6.

30 x 6 = 180

S = Surface area

P = perimeter

H = height

B = area of base

• S=Ph + 2b

(30)(6) + 2(780) = 1740
