Substance a Has a Density of 3 G/cm³ $\frac { V A } { V B } = \sqrt { \frac { 3 } { 4 } }$

Substance A has a density of 3 g/cm³ and substance Bhas a density of 4 g/cm³. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of

A) $\frac { V A } { V B } = \sqrt { \frac { 3 } { 4 } }$
B) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } } = \frac { 1 } { 3 }$
C) $\frac { V \mathrm {~A} } { V \mathrm {~B} } = \frac { 3 } { 1 }$
D) $\frac { V \mathrm {~A} } { V _ { \mathrm { B } } } = \frac { 3 } { 4 }$
E) $\frac { V _ { \mathrm { A } } } { V _ { \mathrm { B } } } = \frac { 4 } { 3 }$
