The density of plutonium is approximately 19,816 kilograms per cubic meter. To convert this to pounds per cubic inch, we first convert kilograms to pounds (1 kilogram is approximately 2.20462 pounds). Then, we convert cubic meters to cubic inches (1 cubic meter is approximately 61,023.7 cubic inches). Therefore, an cubic inch of plutonium would weigh approximately 0.34 pounds.
once cubic inch of plutonuim is about 715 pounds
1 cubic inch = 16,387 06 cm2
Density of plutonium: 19,816 g/cm3
The weight of 1 cubic inch of plutonium = density x volume = 324,726 grams
lead density is 0.41 pounds/cubic inch 1.68 x 0.41 = 0.688 pounds
0.116 pounds per cubic inch
1 US gallon of water weighs 8.33 pounds at 60 degrees F. There are 231 cubic inches of water per gallon, so 8.33 pounds divided by 231 = .03606--> pounds per cubic inch.
TO answer this question, you need to know the density and the volume of the piece of steel. For example, "mild steel" weighs .284 pounds per cubic inch. The volume of a 12 inch x 12 inch x 1 inch piece of steel is 12 * 12 * 1 = 144 cubic inches. .284 pounds/inch^3 * 144 inch^3 = 40.896 pounds. So each of these steel tiles will weigh about 41 pounds.
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic inch.
