Convert the feet and inches into metres and then multiply
Area = 0.5*21*28 = 294 square inches
12' x 21' (252 square feet) = 28 sq. yards.
Curved surface area: pi*21*28 = 1847.256 square cm rounded to three decimal places
Multiply the two dimensions to get the area. The calculation will give you 252 square feet which converts to 28 square yards.
3.11 square yards = 28 square feet.
300 square feet equates to about 28 (27.8709) square meters.
It's 301.3894917.
A 28 meter square is 28 times 28 meters or 784 square meters. If it is one tenth of a meter (10 cm) deep, it has a volume of 78.4 cubic metersIf you mean 28 square meters (like a pool 4 meters by 7 meters) then the volume one tenth of a meter deep is 2.8 cubic meters.
