Find the total surface area of this prism.

a0 square meters

The total surface area is the area of all of the faces of the prism added together.

Rectangles:

2.5 x 10 = 25

1.5 x 10 = 15

2 x 10 = 20

Triangles:

1/2(2 x 1.5) = 1.5

1/2(2 x 1.5) = 1.5

Surface area:

SA = 25 + 15 + 20 + 1.5 + 1.5

SA = 63 m^2

Hope this helps! :)
