you cannot do that; square yards is two dimensios, not three. You would need to know height to get cubic yards

Safra Square was created in 1993.

There are 238*12/(12*12) = 19.833... sq feet.

Give the shape and dimensions to get an answer.

12.96 yards

The question has no sensible answer.

A cubic yard is a measure of volume, not of mass. The two are measures of different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a cubic yard of air. How many kilograms? Next consider a cubic yard of lead. How many kilograms?

The capacity calculator ( see related link) says thirteen for an open room for a standing reception.

Eight to ten if the room has tables or desks for people to sit.

I suppose the figure would depend somewhat on the height of the ceiling and the quality of the ventilation system.

Depens how wide the 640 miles are.

Approximately seven to eight gallons.

85000 sq feet = 85000/9 = 9444.44... sq yards.

It depends on the moisture content of the sand (wet or dry) but as general rule of thumb there is 1.5 tonne of sand per cubic metre or to answer your question correctly 1500Kg per cube.

400 x 225 feet equals 90000 square feet, which equals 2.0661157 acres.

560 sq metres = 0.138 acres (approx).

10 ft * 10 ft = 100 sq ft.

177sq.miles

72 sq metres = 775 sq feet, approx.

4

0.459 sq ft, approx.

600 square feet is 0.014 acres.

Hmmmm, that is a very difficult question. Need to think very carefully about it.

Could the answer, just possibly, be 90 feet?

120 square feet.
