Acone-shaped container with a height of 6 inches and radius of 2 inches is filled with a substance that is worth $5 per cubic foot. find the total value of the substance in the container.

We know that

[volume of a cone]=pi*r²*h/3
r=2 in
h=6 in
[volume of a cone]=pi*2²*6/3> 25.12 in³

1 ft³> 1728 in³
then
X> 25.12 in³
X=25.12/1728> x=0.014537 ft³

if 1 ft³> cost $5
0.014537 ft³> X
X=0.014537*5> x=0.073

the answer is
the total value of the substance in the container is $0.07
