Question

Find the total surface area of the net below.

Answer 1

Total surface area of the triangular prism is  81.6 square m.

Step-by-step explanation:

• b = 3 m

• h = 2.6 m

• p = 3+ 2.6 +2.6=  8.2

• H = 9 m

• SA = bh + pH

    = 3 × 2.6 + 8.2 ×9

    = 7.8 + 73.8

    = 81.6

• Therefore,

• SA = 81.6 square m

• Total surface area of the triangular prism is  81.6 square m.
