None. A hole is the absence of the material.
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.

One cubic meter cannot be "converted" to a square measure unless we know how "deep" it is being spread. For example, if it is one meter deep, then it would cover one square meter; but if it is two meters deep, then it would cover half that area. If it were, say, 1 cm deep, then it could cover a million square centimeters (100 x 100 x 100).

For every meter above the ground , the roots go 3 meters deep . Ceder trees rearly grow higher than 25 meter tall . Thefore the maximum the roots can grow is 72 meters deep .
Assuming 25 meters is round. . . . 123449 gallons.
