Answer:
Mass is 12 kg
Explanation:
By p, did you mean density? If so:
Volume = 4m^3
p = 3kg/m^3
The formula for density is:
[tex]p=\frac{M}{V}[/tex]
Where, M is Mass and V is Volume.
To find Mass we isolate it, so :
[tex]p= \frac{M}{V} \\M= P*V[/tex]
So we subsitute in our mass and density:
[tex]M=3*4=12[/tex]
So we get mass is 12 kg
