Find the total surface area of a triangular prism

surface area = 144

Step-by-step explanation:

To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height.

To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
