Question: what is the surface area of a right trapezoidal prism?
Answer: The width of the four rectangles will be the same as the height of the prism. The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. The surface area can be given with this formula: Surface Area of Trapezoidal Prism = (b1+b2)h + PH.
