0.116 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).
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
156/12 = 13 ft-pounds
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.
lead density is 0.41 pounds/cubic inch 1.68 x 0.41 = 0.688 pounds
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).
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).
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.
120 inch pounds = 10 foot pounds.
28,000 square feet x (8.5 inch / 12 inch per foot) = 19,833.3 cubic ft19,833.3 cubic ft x 62.38 pounds per cubic foot = 1,237,203 pounds1,237,203 pounds / 2,000 pounds per ton = 618.6 tons
1 cubic foot = 1,728 cubic inches
Such that there are 12 inches in one foot, there are 12 inch pounds in one foot pound. Therefore, 5 foot pounds is equal to 12 x 5 = 60 inch pounds.
Convert cubic foot into inches= 1728. Divide 62.5 by 1728 for weight per cubic inch. Multiply weight per cubic inch by 231 (whats in one gallon) which equals 8.355.
Depending on its density, about 0.708lbs per cubic inch. Much heavier than lead.
Using density of steel @ 490.06 pounds per cubic foot (approx) 8 * 10 * (1/12) * 490.06 = 3267.07 pounds (approx)
Pulverised coal = 38 pounds per cubic foot
23*12=276 276*276*6=457056 cubic inches = 264.5 cubic feet 264.5*145 (unreinforced)=38352.5 pounds 264.5*150 (reinforced)=39675 pounds
