Answer:

9.2 + 9.2 + 60 + 75 +75 which is 228.4. Remember to divide the triangles by two after you do base times height.

Answer and Step-by-step explanation:

To find the surface area, we find the area of all the shapes in the prism, then add them together.

Triangles:

(4 × 4.6) ÷ 2 = 18.4 ÷ 2 = 9.2

(4 × 4.6) ÷ 2 = 18.4 ÷ 2 = 9.2

Rectangle 1:

4 × 15 = 60

Rectangle 2 and 3:

5 × 15 = 75

5 × 15 = 75

9.2 + 9.2 + 60 + 75 + 75 = 228.4

228.4 is the total surface area.
