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.

210 cm^2

Step-by-step explanation:

Area1:

6*3 = 18 cm^2

Area2:

6*7 = 42 cm^2

Area3:

6*5 = 30 cm^2

Area4:

6*11 = 66 cm^2

Area5 (*2):

(11+7)*3*1/2

18*3*1/2

54*1/2

27 cm^2 (*2) = 54 cm^2

54 + 66 + 30 + 42 + 18 = 210 cm^2
