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

C. 336 cm^2

Step-by-step 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

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

good luck on your studies! : )
