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.
The density of limestone varies from something on the order of 110 pounds per cubic foot (a shade over 1 ounce per cubic inch) to over 160 pounds per cubic foot (about 1.5 ounces per cubic inch).
lead density is 0.41 pounds/cubic inch 1.68 x 0.41 = 0.688 pounds
On Average it's 450 Pounds
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.
0.116 pounds per cubic inch
If you mean a container with a volume of 1 cubic foot, then: 1/4 inch ball = 0.0082 cu. inch weigh of each ball (steel) = 0.0023 pounds approx. 73.6 balls per cubic inch (allowing for spherical interlocking) 1728 cubic inches ( one cubic foot) x 73.6 x 0.0023 = 292 pounds. So a cu. ft. container will hold close to 300 pounds of quarter inch steel balls.
The given answers are confusing and misuse units. The density at room temperature of the most common isotope of Pu (i.e., 239) is 19.816 grams per cubic centimeter (g/cm^3). One cubic inch equals 16.387 064 cm^3. 19.816 * 16.387 064 = 324.73 g/in^3.
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.
0.283 lb. per cubic inch
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic inch.
0.00397 pounds per cubic inch.
Steel is typically 490 lb/cubic foot. There are 1,728 square inches in a cubic foot which means that each cubic inch weighs about .284 pounds (just a bit over a quarter of a pound per square inch).
