One cubic inch of sapphire weighs approximately 0.51 pounds, or about 231 grams. This is based on sapphire's density, which is around 3.98 grams per cubic centimeter. Since there are 16.387 cubic centimeters in a cubic inch, the weight can be calculated using this density.
A cubic inch of marble typically weighs around 0.31 pounds.
Gray cast iron is around 118 grams per cubic inch.
A cubic inch of 4130 steel weighs approximately 0.283 pounds.
One cubic inch of lead weighs around 0.41 to 0.44 ounces.
The square inch is a unit of area. The cubic inch is a unit of volume; a cubic inch of uranium has a mass of approx. 312,2 grams.
Of course, different brasses and forms can vary, but at a specific gravity of about 8.5, a cubic inch of brass would weigh about 5 ounces (or just under a third of a pound).
About 0.42 ounces. Specific gravity (compared to water) about 0.73
On Average it's 450 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).
The density of lead is 11.34g per cubic centimetre. As there are 16.387 cubic centimetres in one cubic inch, one cubic inch of lead weighs 11.34 X 16.387 or 185.83grams. In ounces this is 6.55 (or just over 6 and a half) ounces.
Density of uranium: 19,1 g/cm3 1 cubic inch = 16,38706 cm3 The mass of 1 cubic inch of uranium is 313 g.
The density of thallium is 11.85 gm/cc, or 11.85 times the density of water.After some massaging, that converts to 6.847 ounces per cubic inch.
