Surface area = 2(base area) + (perimeter of base) x (height)
Surface area = 2(9 x 4.0) + (9 + 8.1 + 8.1) x 4.0
Surface area = 144 + (25.2) x 4.0
Surface area = 144 + 100.8
Surface area = 244.8

AAAaannndd the bot gets it wrong yet again!
2(9 x 4.0) + (9 + 8.1 + 8.1) x 4.0 = 172.8
2(9 x 4.0) + (9 + 8.1 + 8.1) x 4.0 = 172.8
