Volume = 1240.5 = 24 cubic feet is needed
An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.
26 inches = 2feet 2inches
50 pounds covers 0.5 cubic feet. Since the depth is 3 inches, or 1/4 foot, you can cover 0.5/.25 = 2 square feet of area. That is not very much.
A rectangle area that is 12 feet by 14 feet by 6 inches deep is equal to 3.11 cubic yards. This job would require 4.2 tons of gravel.
16' x 16' x 0.5' = 128 cubic feet

An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.
There is no dirt in a hole that is 3 feet deep and six inches in diameter.
26 inches = 2feet 2inches
This question is about a cubed area. First convert the inches to feet--18 inches is 1.5 feet. Then multiply all three numbers by each other. 15*12*1.5 is 270. You will need 270 cubed feet of dirt to fill the area.
240 x 3 /12 Cubic feet = 60 cubic feet
You will need 1500 cubic feet.
50 pounds covers 0.5 cubic feet. Since the depth is 3 inches, or 1/4 foot, you can cover 0.5/.25 = 2 square feet of area. That is not very much.

about 17 yards of concrete (it's sold by the cubic yard)
If you mean 12 feet long by 8 inches wide by 4 inches deep, you will need at least 0.1 cubic yards
16' x 16' x 0.5' = 128 cubic feet
