Answer:
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

Volume is the amount of space occupied by an object or a material. Volume is said to be a derived unit, since the volume of an object can be known from other measurements. In order to find the volume of a rectangular box, for example, one only needs to know the length, width, and depth of the box. Then the volume can be calculated from the formula, V = l× w× d. Specifically, if the length (l) is 30 centimeters, width (w) is 20 centimeters, and depth (d) is 10 centimeters, then the volume is: V = 30 centimeters x 20 centimeters x 10 centimeters = 6,000 cubic centimeters.
