Question

Can someone help me do this i am very stuck and my friends don't know how to find the surface area for this triangular prism

Answer 1

C. 336 cm^2

Explanation:

So you are basically just finding the area of each shape and adding them together.

Rectangle on the left: 6 x 12 = 72cm

Triangles: 6 x 8 = 48cm

Middle Rectangle: 8 x 12 = 96cm

Right Rectangle: 10 x 12 = 120 cm

72cm + 48cm + 96cm + 120cm = 336cm^2
