It would not weigh anything because there is no dirt inside of a hole.
Th weight of dirt to be removed to make the hole is 1800 lbs. Of course there is no dirt in the hole when it is done, so Zero lbs.
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)
Because a square meter is two dimensional and a cubic meter is three dimensional, there would theoretically be an infinite number of square meters within a cubic meter.
No such unit exists because it is similar to molar quantity measured in moles(mol) for the same material, mass is directly proportional to volume. like cubic hectolitre, square teralitre, square nanolitre etc. are not used for the same reason a cubic gram does not make sense because if you think a cubic gram is three dimensions (also a cubic kilogram) because a cubic meter is three dimensions, you are wrong. Mass depends on three dimensions. i.e. volume.
12 cubic feet
No. They are different. A square mile is two dimensional and a cubic mile is three dimensional. A square mile is length times width, and a cubic mile is length times width times height.
A three-dimensional volume (cubic meters) cannot be converted to a two-dimensional area (square meters).
5.25 lbs.
The area of an object in three dimensions will be measured in cubic feet. 1600 cubic feet.
no, cubic units are for three dimensional figures, hence cubic = 3 they are measured in square units, as they have only two dimensions.
Cubic means a three-dimensional volume. Square means a two-dimensional flat area. One cannot be converted to the other.
Glass weighs 162 pounds per cubic foot. Tempering adds no weight. Glass is glass, except specialty glasses like high temperature glass, which weighs slightly more.
Cubic means a three-dimensional volume. Square means a two-dimensional flat area. The area that can be covered by a cubic yard of rock will depend on how deep the rock bed will be.
