Answer:
SA = 742
Step-by-step explanation:
H*L + H*W + L*W = SA
(8 x 6) x 2= 96
(22 x 6) x 2 = 264
(8 x 22) x 2 = 352
96 + 264 + 352 = 742
712 cm^2
Surface area
Base and Top .......... 2 (8*6) = 96 (cm*2)
2 sides .......... 2 (22*6) = 264 (cm^2)
Front and Back ......... 2 (8*22) = 352 (cm^2
Total 96+264+352 = 712 cm^2
