Brass is an alloy of copper and zinc. The relative proportions are varied to make brass with different properties. The different mixes result in different densities, but they are close to 0.3 pounds per cubic inch.
2.54 grams/cubic inch
13.6 grams/ccSame as the density of 1 cc, 72 pounds, 5 gallons, or a school-bus full of mercury.
0.283 pounds 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.
Let's assume that the density of marble is 2.76 gm/cm3. Marble varies somewhat in density depending upon the type of marble; so your marble may vary from this number. 0.75 inch X 1 square foot X 144 square inches/square foot = 108 cubic inches 2.76 gm/cm3 X 16.39 cm3/cubic inch X 108 cubic inches = 4886 gms 0.00220 pounds/gm X 4886 gms = 10.7 pounds
There is no such thing as a 'cubic square inch'. The density of aluminum is 0.0858 pound per cubic inch. (rounded)
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic 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
one -tenth of a pound ( 0.1 pounds) since it has a density of 0.1 pounds per cubic inch
Since brass is made by combining differing amounts of copper and zinc, there is no uniform density per cubic inch. Therefore, you will have to conduct experiments to deduce this amount for yourself.
Stainless Steel 321 has density of 0.29 pounds per cubic inch, which is 8.0272 grams per cubic cm.
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.
Divide 4.6 lbs by the lead density in lbs/cubic inch
Those are incompatible units. Pounds per square foot is pressure. Pounds per cubic foot is density. It is like converting gallons to inches.
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
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.
