A object weighing 10 pounds with a volume of 1 cubic foot will sink until
0.16 of its volume is under water, and the remaining 0.84 of its volume is
above the surface. At that point, the weight of the displaced water is
(0.16 cubic foot) x (62.5 pounds/cubic foot) = 10 pounds,
and the object will float at that depth, and sink no further.
Those are incompatible units. Pounds per square foot is pressure. Pounds per cubic foot is density. It is like converting gallons to inches.
A square yard is a measurement in 2 dimensions, length and width. Since there is no depth measurement in a square yard, therefore, a square yard of water has no weight. However, "...a cubic yard is 27 cubic feet, and a cubic foot of water weighs about 62.4 pounds, so 62.4 x 27 gives you...about 1685 pounds." (http://saluqi.home.netcom.com/ticklinx1.htm)
Pulverised coal = 38 pounds per cubic foot
46-0-0 weighs between 45 and 52 pounds per cubic foot
There are approximately 43 pounds per cubic feet of potatoes. Thus there are 8000 X 43 = 344,000 pounds of potatoes in 8000 cubic feet.
Those are incompatible units. Pounds per square foot is pressure. Pounds per cubic foot is density. It is like converting gallons to inches.
Typical window glass weighs 156 pounds per cubic foot. For comparison, a cubic foot of aluminum weighs about 168 pounds, and a cubic foot of oak is around 50 pounds.
Depends on whether it's a cubic foot of feathers or a cubic foot of lead.
A 2500 square foot area x 4' deep is 10000 cubic feet. So you need 10,000 cubic feet of sand. Dry sand has a density of 80-100 pounds or so per cubic foot, so that's somewhere between 800,000 and a million pounds of sand.
28,000 square feet x (8.5 inch / 12 inch per foot) = 19,833.3 cubic ft19,833.3 cubic ft x 62.38 pounds per cubic foot = 1,237,203 pounds1,237,203 pounds / 2,000 pounds per ton = 618.6 tons
0.116 pounds per cubic inch
150 pounds That is 1 cubic foot and concrete weighs 150 pounds per cubic foot
The answer depends on the density of the rock. A cubic foot of pumice, for example, can have a mass of around 15.6 pounds whereas minerals rich in metals such as iridium will have mass exceeding 1200 pounds.
that is 333 cubic feet,or 12.3 cubic yards At 100 pounds per cubic foot,that is over 33,000 pounds of gravel
1 cubic foot of water weighs about 62.458 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.
A yard of concrete is a measure of volume. A square foot is a measure of area. A cubic yard is 27 cubic feet of stuff. (3x3x3)To relate volume to area you must extend the area over a third dimension. One square foot that is one foot deep will equal one cubic foot. (1x1x1)So, a yard of concrete is 27 cubic feet or 3 feet tall 3 feet wide 3 feet deep. concrete wieghs 150lbs per cubic foot 27cubic feet times 150 pounds is 4050 pounds. This is 1 cubic yard of concrete.
