(36m^2)*(0.5m) = 18m^3
Yes.
Gravel is bought in cubic quantities, or by weight. You ask "to fill" but you only give a square measure. The volume of gravel required wil depends on the depth you wish the gravel to be. To fill 81 square metres to a depth of 5 cm would require 4.05 cubic metres of material.
It depends on the depth to which the area is filled.
40000 liters calculation: 8m x 5m x 1m = 40 meters cubed 1 meter cubed = 1000 liters of water so 40 cubic meters = 40000 liters of water
It will hold 216 cubic metres.
23*38*4.5 = 3933 cubic meters are needed
Calculating that is a CUBIC measurement, which means you need a value for width, Length and depth. in metric measure it is easier than English standards .. Once you have those three just multiply the three & you will know how much you need. IF your fill area is 2 Meters wide, 3 meters long and 1/2 meters deep the equation calculates like this (2X3X .5)=3 cubic meters Hope that helps
Volume of sand required = 7 ft * 7 ft * 1/6 ft = 49/6 cubic feet = 8.166... cubic ft.
To figure the volume, you would need to know the height. The formula for volume is length X height X depth. Here is an example: Length: 12.051m Width: 2.340m Height: 2.380m 12.051 x 2.340 x 2.380 = 67.11 cubic meters Drop roughly 5 cubic meters to be safe with your capacity if you are planning a shipment, as you cannot always fill up to the top.
72 cubic feet
The answer is 23*38*4.4 = 3845.6 cubic metres.
10' x 5' x 4' is 200 cubic feet which equates to 5,663.4 liters.
