If a lead pipe 1/4 in. thick has an inner diameter of 1 1/2 in.,
find the number of cubic inches of a lead in a piece of pipe 10 ft. long.
:
convert 10 ft to inches
12 * 10 = 120"
Find the inner radius:
* = (.75")
The overall radius of the pipe, add 1/4 inch:
.75 + .25 = 1"
:
Find volume of the lead
lead vol (V) = Overall volume - inner volume
V = -
V = 377 - 112 = 265 cu/in of lead
