1) volume= volume of prism+ volume of cuboid

(l*w*h)+(l*w*h)

V=(12*4)*9+(16*4*6)=816 ft^3

2)volume=(pi*radius*radius)+ (4/3)*pi*r^3, here radius=r=6

=1017.36m^3

3)(1/2)*(4/3)*pi*r^3+(8*8*12), here r=4

901.97cm^3

4) almost similar to (1), V=(14*9*5)+(8*14*9)

1638 in^3

5) V=(l*w*h)+(l*w*h)=(5*5*7)+(13*7*4)

539 mm^3

6) V=(1/2)*(4/3)*pi*r^3+[(h/3)*pi*r^2], here h=15,r=10

3663.33cm^2

Can u please draw the formula on a paper an take a picture I don't entirely understand

Thx
