There are 3,170.0646 US gallons of water in 12 cubic meters.
12 cubic meters = 423.78 cubic feet.
12*15*0.1=18 18 cubic meters
12,000,000 cubic centimeters.
It will hold 216 cubic metres.
Volume = 1.25 x 2 x 3.14 x 12 = 94.2 cubic meters 94.2 cubic meters = 20724 gallons
A cubic metre is a unit of volume. A square metre is a unit of area. The two units are therefore incompatible.
4 m diameter x 12 m long = (Pi/4)*4*4*12 = 48*Pi cubic metres = 150.79645 cu.m. (Almost 150.8 tonnes of water).

Assuming a typical wheelbarrow holds around 0.05 cubic meters, you would need around 2,000 wheelbarrows to move 100 cubic meters of material.
To calculate the volume of dirt in the hole, you multiply the length, width, and depth together. Therefore, the volume of the hole would be 6 meters x 2 meters x 1 meter = 12 cubic meters. Thus, there are 12 cubic meters of dirt in the hole.
