Question

What is the CGS unit of volume?

Answer 1

Volume is basically the 3-D space enclosed by an object. The CGS unit of volume is Liter. CGS is abbreviated as centimeter-gram-second unit system. There also exists SI unit which stands for System International Unit.

Complete answer:
Volume is the amount of space occupied by an object. It is given as the product of length, width and height i.e.
Volume$=$length$\times$width$\times$height
$=$l$\times$b$\times$h(b$-$breadth or width)
Length, breadth and height all are measured in meters, so SI unit of volume is cubic meter or ${{\text{m}}^{3}}$. The CGS unit then becomes $\text{c}{{\text{m}}^{3}}$. The conversion of I meter into centimeter is given as 1m = 100 cm. So unit of$1{{\text{m}}^{3}}$ will become ${{\left( 100\text{cm} \right)}^{3}}=\left( 100 \right)\text{c}{{\text{m}}^{3}}={{10}^{6}}\text{c}{{\text{m}}^{3}}$. We have I liter equals to thousand cubic centimeters. So, we can say that CGS unit of volume is Liter or cubic centimeter.

Note:
Volume can be easily found by measuring the dimensions of the object. There are different formulas of volume for different shapes of objects. Like volume of cylinder is given as $\text{ }\\!\\!\pi\\!\\!\text{ }{{\text{r}}^{2}}\text{h}$ where ‘r’ is the radius of cylinder and ‘h’ is its height, volume of sphere equal $\dfrac{4}{3}\text{ }\\!\\!\pi\\!\\!\text{ }{{\text{r}}^{3}}$. Other units in which volume can be measured include gallon, quart, fluid ounce, barrel, pint, etc. Gallon is a mostly used unit of volume in the United States. One US liquid gallon equals 3.785 liters. Fluid ounce is mainly used for measuring liquids.
