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


ANSWER

$$373.7\ m^3$$


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  $$V = 373.7 \ m^3$$
