Divide 4.6 lbs by the lead density in lbs/cubic inch
244.5 (rounded)
Uranium has a density of 19 grams per cubic centimeter, so you'll have to convert the grams to pounds and the cubic centimeters to cubic inches. Since 1g = 0.00220462280lb, then 19g = 19 x 0.00220462280lb, which = 0.041887833lb, or about .042lb. Now convert cubic centimeters to cubic inches: 1 cubic centimeter = 0.061023744100 cubic Inches = about .061 cubic inches 19g/cc is the equivalent of .042lb/.061 cubic inches, which divides out to about .69 pounds per cubic inch.
None, since there can be no such conversion.A pound is a measure of mass. A cubic foot is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a cubic foot of water. How many pounds? Next consider a cubic foot of lead. How many pounds?
Depends on whether it's a cubic foot of feathers or a cubic foot of lead.
* I Imperial gallon = 1.2 US gallons * I cubic foot = 1,728 cubic inches 1 Imperial gallon = 277.4 cubic inches(approximately) 2,000 Imperial gallons = 321.08731 cubic feet = 554,838.9 cubic inches I US gallon = 231 cubic inches (approximately) 2,000 US gallons = 267.36111 cubic feet = 462,000 cubic inches
According to my calculations, 2.44 in3 of lead would weigh one pound.
1,728 cubic inches.
There are 1,728 cubic inches in a cubic foot.
There are 1,728 cubic inches to the cubic foot
14.8 cubic feet = 25,574.4 cubic inches.
1728 cubic inches = 28316.8 cubic centimeters
1,213,056 cubic inches of water is 5,251.3 gallons. Each gallon of plain water weighs about 8.345 pounds. So, 5,251.3 x 8.345 = about 43,822.1 pounds or about 21.9 tons.
