Volume =12*4*6.3 = 48*6.3 =302.4 In3

Surface area

=2* (4*6.3+12*6.3+12*4) = 2* (25.2+75.6+48)= 2*148.8 =297.6 in2

Volume = 3.14*52*12 = 300*3.14 = 942 m3

Surface area = 2*3.14 * 12*5 =376.8 m2

Total surface area = 2*3.14 *52 +376.8 = 50*3.14+376.8

= 157+376.8 =533.8m2

Volume = 12*4*11+2/3 *3.14 * 63 = 528+144*3.14=528+452.16

=980.16 =980.2 in3
