Vedclass · Answer

(A) The side length of the cube is $l = 1.2 	imes 10^{-2} \; m$.The volume of a cube is given by $V = l^3$.Substituting the value: $V = (1.2 	imes 10^{-2} \; m)^3 = (1.2)^3 	imes (10^{-2})^3 \; m^3 = 1.728 	imes 10^{-6} \; m^3$.According to the rules of significant figures,the side length $1.2$ has two significant figures. Therefore,the result should be rounded to two significant figures.Rounding $1.728$ to two significant figures gives $1.7$.Thus,the volume is $V = 1.7 	imes 10^{-6} \; m^3$.

$A$ cube has a side of length $1.2 \times 10^{-2} \; m$. Calculate its volume.
