Answer explanation

This is a triangular prism, the base is a triangle, not the rectangle!

Area of the triangle is bh/2 so 2(2)/2=2, Perimeter of the base is the distance around the triangle, 2+2+2.8 = 6.8, and height is the distance between the two bases, 5. So,

SA = 2B + Ph

SA = 2(2)+6.8(5)

SA = 38

V = Bh

V = 2(5)

V = 10
