Re: solve & explain

A cubic meter is a cube with each side measuring 1 meter or 100 centimeters.   Volume of a cube is length * width * height.   So 1 meter * 1 meter * 1 meter = 1 cubic meter.   Or 100 cm * 100 cm * 100 cm = 1000000 cubic centimeters.

A cube with sides of 10 cm has a colume of 1000 cubic centimeters (10 * 10 * 10).   1000 cubic centimeters is 1/1000 of 1000000 cubic centimeters (cubic meter).
