If there are two metal blocks a and B, the density of a is 2 / 3 of that of B, and the mass of B is twice that of a, then the volume of a is the same as that of B___ ?

If there are two metal blocks a and B, the density of a is 2 / 3 of that of B, and the mass of B is twice that of a, then the volume of a is the same as that of B___ ?

Let the density of B be p, then the density of a is 2P / 3;
Let the mass of a be m, then the mass of B be 2m;
From volume = mass / density
So the volume of a is 3m / 2p, and the volume of B is 2m / P
So the volume of a is 3 / 4 of that of B
