The density of steel is typically around 490 pounds per cubic foot in English units.
To calculate the volume of the steel ingot, we need to know the density of steel. The density of steel is around 0.284 pounds per cubic inch. Therefore, to find the volume in cubic inches, we divide the weight (4000 pounds) by the density (0.284 pounds per cubic inch) to get 14,084.5 cubic inches. Finally, to convert cubic inches to cubic feet, we divide by 1728 (since 1 cubic foot = 1728 cubic inches), resulting in a volume of approximately 8.15 cubic feet.
Units of density are mass per unit volume. Unit volume might be a cubic centimeter or a cubic foot, for example. Whatever the size of your sample, a cubic foot of it is always a cubic foot, and the mass of that cubic foot will always be the same.
Using density of steel @ 490.06 pounds per cubic foot (approx) 8 * 10 * (1/12) * 490.06 = 3267.07 pounds (approx)
The density of aluminum is approximately 0.098 pounds per cubic inch. To convert this to pounds per cubic foot, you would first convert cubic inches to cubic feet (1 cubic foot = 1728 cubic inches) and then multiply by the density in pounds per cubic inch. Therefore, the density of aluminum in pounds per cubic foot is approximately 169 pounds per cubic foot.
The weight of tube steel can vary depending on its dimensions and thickness. Generally, the weight of tube steel is calculated by multiplying the volume of the tube by the density of steel, which is around 490 pounds per cubic foot.
The weight of a cubic foot of stainless steel is around 494 pounds.
Steel has a Specific Gravity of 7.83. This means that a cubic foot of steel weighs 7.83 times more than a cubic foot of water (which weighs 62.4 pounds)
It could be pounds per cubic inch, or pounds per cubic foot, or tons per cubic yard. The only substance I know in fps is water which is 62.4 pounds per cubic foot.
If the density is 20 pounds per cubic foot, then each cubic foot you have will weigh 20 lbs. However you are told that you have 30 cubic feet so :-30 * 20 = 600 lb.
