Answer:
Volume = 40 cm³
Explanation:
Density = Mass/ Volume..........(1)
If Density = 0.5 g/cm³
and Volume = 80 cm³
Substituting these values into equation (1) to get the mass
0.5 = Mass/80
Mass = 0.5 * 80
Mass = 40 g
Now if density = 1 g/cm³
The mass of the wood remains constant, therefore, Mass = 40 g
Again to get the volume put the values for mass and volume into equation (1)
1 = 40/volume
Volume = 40/1
Volume = 40 cm³
