Answer:

  • 93 in²

Step-by-step explanation:

Given triangular prism with:

  • a = 1.5 in, b = 2 in, c = 2.5 in, l = 15 in

Total surface area is:

  • A = Pl + 2B, where P is the perimeter of base, B is area of base

Considering all given values we have:

  • A = (1.5 + 2 + 2.5)*15 + 2*(1/2*1.5*2) = 93 in²
