Find the surface area of this triangular prism 138 square centimeters 144 square centimeters 132 square centimeters 156 square centimeters class=

Respuesta :

Step 1) Find the area of the triangles

1/2(3 x 4) = 6

1/2(3 x 4) = 6

Step 2) Find the area of the rectangles

5 x 11 = 55

4 x 11 = 44

3 x 11 = 33

Step 3) Find the total surface area

SA = 6 + 6 + 55 + 44 + 33

SA = 144 square centimeters

Hope this helps! :)
