That completely depends on what substance fills the cubic feet.
If it's air, then there are very few kilograms of mass in that space.
If it's water, then there are about 453 kilograms of mass in that space.
It's it's stones or gold, then there are a lot more kilograms of mass in it.
If the cubic feet are empty, then there are no kilograms in them at all.
Depends on the density of the material that takes up that space. 7 cubic ft of lead weighs more than 7 cubic ft of styrofoam
You can't convert between units that measure completely different things. Kilogram is a unit of mass, cubic foot is a unit of volume.
A yard is 3x3x3 = 27 cubic feet, so 7 yards is 7x27=189 cubic feet
40 feet x 7 feet x 7 feet = 1960 cubic feet.
7.5 cubic feet = 0.27 cubic yards.
1,000.6 cubic feet of volume.
7 cubic meters is 247.2 cubic feet.
There are: 20*4*7 = 560 cubic feet
The accepted capacity for washer-extractors is between 5 and 7 lb. per cubic foot. Accepted capacity for dryers is between 2.5 and 3.5 lb. per cubic foot.
4' x 4' x 7' = 112 cubic feet
5.55
7 feet by 14 feet = 98 square feet 98 square feet by 4 feet = 392 cubic feet There are 9 square feet in a square yard, and there are 29 cubic feet in a cubic yard.... so 392 cubic feet = 14.519 cubic yards
One thousand seventy-six cubic feet
It is: 10*7*3 = 210 cubic feet
