8 ft

Answer 1

Step-by- step explanation : Perimeter of the triangular base=10+10 + 16 =36 ft Height of the prism n = 15ft Base area = Area of the triangle = 1 2 (Base)(Height ) = 1 2 (16)(6); =48 square ft Surface area of the triangular ism = 2(base area) + (perimeter * heig ) =2(48); + 36 * (15) = 96 + 540 =636
