I NEED AN ANSWER QUICK! What is the surface area of the right trapezoidal prism? To receive credit, you must show the work used to arrive at a final answer. (And PLEASE show work)

210 cm²

Step-by-step explanation:

Area of the surface having dimensions 6 cm × 11 cm

= 11 × 6 = 66 cm²

Area of the surface having dimensions 3 cm × 6 cm

= 3 × 6 = 18 cm²

Area of the surface having dimensions 7 cm × 6 cm

= 7 × 6 = 42 cm²

Area of the surface having dimensions 5 cm × 6 cm

= 5 × 6 = 30 cm²

Area of the trapezoidal surface on the top =

=

    = 27 cm²

Area of the trapezoidal base = Area of the surface on the top = 27 cm²

Total surface area =

                                               = 210 cm²

Therefore, total surface area of the trapezoidal prism = 210 cm²

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
