Please help!

Right prism with height of 10 and side length of 6. Find the surface area! (Picture of triangle isn’t included you have to draw it out then solve)

Answer 1

The area of each base = 1/2 * 6 * sqrt(6^2 - 3^2)
                                    =  3 * sqrt 27
                                    =  9 sqrt3

Total surface  area = 3 * 6*10 + 2*9 sqrt3
                             =  180 + 18sqrt3
                             =  211.2 ins^2   to nearest tenth.
