100 ibs. per ft cubed
Depending on type of compost, density and moisture content 1 cubic foot of compost will weigh about 10 to 11 pounds.
Just short of 11,000 pounds roughly. Average density of granite is about 2.7 g/cm3.
14.1 pounds for a 12" x 12" x 1" .
Cubic feet is a measure of volume (i.e. a cube measuring one foot x one foot x one foot). Pounds is a measure of weight (mass). Therefore the relationship between cubic feet and pounds is called density (lbs per cubic foot) and will vary for each substance: a gas (at atmospheric pressure) will have less than one pound per cubic foot, while a block of wood will have a density of approximately 60 lbs per cubic foot.
Since the "per cubic foot" unit is the same, the conversion is just pounds to kilos and that is just to divide by 2.2.62.4 / 2.2 = 28.36kgI am a little concerned that you may have read the problem wrong and need not kg/ft3 but kg/m3Check on it.
155 pounds per 4.2 ft cubed = 155/4.2 = 36.905 pounds per cubic foot.
The two units are not equivalent. "cm cubed" is a unit of volume whereas "pounds per cubic foot" is a unit of density. If the question was changed to: "what is 5022 g/cm3 in pounds per cubic foot?" where g/cm3 stands for grams per centimetre cubed, then: 1 g/cm3 = 62.42796 pounds per cubic foot therefore: 5022 g/cm3 = 313513.2 pounds per cubic foot
Kilograms per meter cubed (kg/m3) or pounds per cubic foot (lb/ft3)
A cubic foot of aluminum weighs 168.48 pounds.
40 pounds per cubic foot equates to 640.74 kg per cubic meter.
Aluminum has a density of 2.7 g/cm^3 1 inch is 2.54 cm. So, a cube of aluminum with a volume of one cubic inch has a volume of 16.39 (rounded to hundredths place) cm^3 Multiply that by 2.7 g/cm^3 and you get 44.25 g. Since your original question was in inches, I assume you want the answer in ounces. So, the final answer is this: One cubic inch of aluminum weighs 1.56 ounces.
1500 pounds
Density is mass/Volume so you must include the units of measurement. For mass, these may be grams or kilograms (or, in countries still using the Imperial system, pounds!). Similarly there are measures for volume. If these were not given it would not be possible to tell whether the density was given in grams per cm3 or pounds per cubic foot.
0.0765 pounds per qubic foot
one foot of 2-inch diameter aluminum rod = 22 / 6 = 3.66667 lbs 3.66667 x 15 feet = 55 lbs
168.5 pounds (roughly)
There are 62.4 pounds of water in a cubic foot. Fish have about the same density as water, so probably about the same.
