Acube measuring 2cm on each side and weights 5g what is the density of the of the cube g\cm3. will it sink or float

1) we calculte the volume of this cube.
Volume of a cube=side³
Data:
side: 2 cm

Volume =(2 cm)³=8 cm³

2) we calculate the density.
density=mass/ volume
Data: 5g
volume=8 cm³

Density=5 g/8 cm³=0.625 g/cm³

3)we compare the density of this cube and the density of the water.
Density of the water= 1 g/cm³
Density of this cube=0.625 g/cm³

Because the density of the cube (0.625 g/cm³) is less than the density of the water (1 g/cm³), the cube will float.

the cube will float.
