Calculations and measurements of volume are used in medicine architecture science construction and business. Gasses and liquids such as propane gasoline and water are sold by volume as are many groceries and construction materials. Fundamental Mathematical Concepts and Terms UNITS OF VOLUME Volume is measured in units based on length cubic feet cubic meters cubic miles and so on. A cubic meter for instance is the amount of volume inside a box 1 meter m tall 1 m wide and 1 m deep. Such a box is a 1-meter cube so this much volume is said to be one cubic meter. An object doesn t have to be a cube to contain a cubic meter one cubic meter is also the space inside a sphere 1.24 meters across. Cubic units are written by using exponent notation that is 1 cubic meter is written 1 m3. This is why raising any number to the third power that is multiplying it by itself three times as in 23 2 X 2 X 2 is called cubing the number. Volume VOLUME OF A BOX There are standard formulas for calculating the volumes of simple shapes. The .
