# Each side of a cube is measured to be $7.203\ m$.The volume of the cube to appropriate significant figure is:

$373.7\ m^3$

##### SOLUTION
Side of cube  $a = 7.203 \ m$
Volume of cube  $V = a^3$
$\implies \ V = (7.203)^3 = 373.714 \ m^3$
Since the value of side of cube has 4 significant figures, thus the value of volume of cube must also have 4 significant figure.
Thus volume of cube  $V = 373.7 \ m^3$
