There is no such thing as a 'cubic square inch'.
The density of aluminum is 0.0858 pound per cubic inch. (rounded)
Take the density of water as 1 gram per cubic centimeter. With 1 meter = 100 cm, then a 1 meter tall column of water with cross sectional area of 1 cm2 has a volume of (1 cm2)x(100 cm) = 100 cm3. So this column of water has a mass of 100 grams. 1 kg = 1000 grams, so 100 grams = 0.1 kg. Therefore it is 0.1 kg per cm2.
Cubic or cubed eg volume is measured in cubic centimetres, sometimes referred to as centimetres cubed (cm3)
Convert 40 ft to inches , by multiplying by '12' Hence 12 x 40 = 480 ins. Multiply together the three numbers in inches 48 X 480 x 3.5 = 80640 cu. ins. There are 36 x 36 x 36 = 46656 cu.ins in 1 cu.yds. Hence 80640 cu. ins x 1 cu. yd / 46656 cu. ins = 1.72839 cu.yds.
* A cubic sequence is a sequence in which the third level of differences (D3) is constant. * It is represented by the function tn=an3+bn2+cn+d, where D3=6a, and a does not equal zero.
The volume is 8 cubic cm.
Those are incompatible units. Pounds per square foot is pressure. Pounds per cubic foot is density. It is like converting gallons to inches.
14,300 pounds. Sand has a density of 100 pounds per cubic foot.
The aluminium density is 2,7 g/cm3. Mass = volume x densitySo, the mass is 76,455 kg.
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.
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic inch.
Stainless Steel 321 has density of 0.29 pounds per cubic inch, which is 8.0272 grams per cubic cm.
You need to find the density of helium in pounds per cubic foot. Then since density is mass/volume, divide the mass by the density. You may find getting the density into the units you need to use a challenge.
0.4 pounds per cubic feet - a very massive gas!
g/c3 (grams per cubic centimeter) or lb/ft3 (pounds per cubic foot)
The density is 50 lbs/yards3
The density of PVC is 1390kg/m3
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.
