Question

A composite figure is made up of a triangular prism on top of a rectangular prism. Which of the following surface area equations could you use to find the total surface area of the solid? Select all that apply. SA = 2l + l2 SA = 2rh + 2r2 SA = 4r2 SA = r + r2 SA = 2lw + 2lh + 2wh SA = 2B + Ph

Answer 1

Answer:In this problem the surface area of the composite figure is equal to the area of the base of the rectangular prism plus the lateral area of the rectangular prism, plus the area of the two triangular faces of triangular prism, plus the area of two rectangular faces of the triangular prism.
