lead density is 0.41 pounds/cubic inch 1.68 x 0.41 = 0.688 pounds
1 cubic inch of lead has a weight of approx 13.11 pounds weight.
Depends on whether it's a cubic foot of feathers or a cubic foot of lead.
l= .5 in d= .312 in dxdx .7854 x .5 = .0382269 cubic inches or .0000221 cubic feet multiplied by the known weight of lead (712 lbs/cubic foot) .0157352 pound lead cylinder
First find the volume, then multiply by the density of lead. Density of lead = 0.41 pounds per cubic inch.Volume = (area of base) * (length) = (pi * r2) * (length) = 3.14 * (0.75 in / 2)2 * (3 in) = 1.32 in3. Then (0.41 lb / in3) * (1.32 in3) = 0.54 pounds, or 8.6 ounces
Divide 4.6 lbs by the lead density in lbs/cubic inch
lead density is 0.41 pounds/cubic inch 1.68 x 0.41 = 0.688 pounds
A cubic inch of lead is about 0.4 pounds. So 10 pounds would be about 25 cubic inches which would make a ball about 3.6 inches in diameter. That is slightly larger than a softball.
That depends on what this is a half-cubic foot OF. Feathers? Lead? Helium? It makes a difference.
1 cubic inch of lead has a weight of approx 13.11 pounds weight.
This question cannot be answered sensibly. A cubic foot is a measure of volume, with dimensions [L3]. A pound is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information. It takes only a little mental effort to compare a cubic foot of air and a cubic foot of lead and come to the conclusion that the two will have very different masses.
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?
The weight of a lead ball with a 57-inch diameter would depend on the density of lead, which is approximately 709 pounds per cubic foot. Using the formula for the volume of a sphere (V = 4/3 * π * r^3) and the density of lead, you can calculate the weight to be around 8,066 pounds.
