Answer 1

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
