Find the surface area of the right prism with the given features.

Question

The bases are right trapezoids with bases of lengths 8 and 14 perpendicular to one side of length 18; height = 11.

Answer 1

so, the area is two trapezoids and four rectangles

2[(8+14)/2 * 18] + 8*11 + 14*11 + 18*11 + 11√(6^2+18^2)
