Respuesta :

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.

answer: the cube will float.
