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.
3 meters is approximately 9'10" (9 feet, 10 inches)
10 x 20 x 1
10*5*3 = 150 cubic metres
If the 25 meters is a circle, it would be 68256 gallons

Assuming 25 meters is round. . . . 123449 gallons.
10*5*3 = 150 cubic metres
3 meters is about 10 feet.
If the 25 meters is a circle, it would be 68256 gallons
If it is the same depth everywhere, then V = lwd 2500 = 25x10xd d = 10 m that is a deep pool
10 yards = 9.144 meters
One atmosphere of pressure is equal to the pressure at sea level. Therefore, 100 atmospheres would be roughly equivalent to the pressure experienced at a depth of about 3,000 feet (914 meters) underwater.
The Earth's crust varies in thickness, but on average it is about 30 kilometers (18.6 miles) deep beneath the continents and about 5-10 kilometers (3-6 miles) deep beneath the ocean floor.
10 acres = 40,468.56 square meters.
