Volume is length multiplied by length multiplied by length. You may have heard that volume is length times height times width, but it means the same thing. ( V= l l l ) You may think of a volume as the space inside a rectangular (block-shaped) fish tank. Volume is the measure of an amount of space in three dimensions. Because volume is such a common type of measurement, it is unique in that it has two types of commonly used root word in both metric and English systems. The metric roots are liter (L) and cubic meter (m3). The English system also uses cubic length, such as cubic feet (ft3) and an extensive array of units that are not in the cubed length format, such as teaspoons, tablespoons, cups, pints, quarts, and gallons. Again, analogously to area measurements, a cubic meter is a meter multiplied by a meter multiplied by a meter, and a cubic foot is a foot by a foot by a foot.
