A. 255cm ^2
B. 216cm ^2
C. 144cm ^2
D. 256cm ^2

Answer 1

5 times 12 twice for the side 6 times 12 for the base and and 4 times 6 twice
120+72+24=216^2

Answer 2

B. 216

Explanation:

the formula for this is (S1+S2+S3) L+ BH

so when we plug that in it would be

(5+6+5)12+6*4

and when that is solved it ends up being 216
