1172. 08 in²
- Step-by-step explanation:
Hi there !
A(prism) = 2(lw + lh + wh) - Ab(cylinder)
= 2(16*11 + 16*11 + 11*11) - πr²
= 2(176 + 176 + 121) - 3.14*16
= 2*473 - 50.4
= 946 - 50.24
= 895.76 in²
A(cylinder) = πr² + 2πr*h
= 3.14*16 + 2*3.14*4*9
= 50.24 + 226.08
= 276.32 in²
A(total) = 895.76in² + 276.32in² = 1172.08 in²
Good luck !
