Question

The mass of a tennis ball is 57.8 g. The volume is 149 cm3.

Answer 1

:

The tennis ball will float in water because it has a density of 0.388 g/cm3 (approx)(round to the hundredths place).

Explanation:

Density = mass/volume.

The mass of a tennis ball is 57.8 g.

The volume is 149 cm3.

.: Density = 57.8/149

= 0.388 g/cm3 (approx).

Thus,

Objects that float all have densities of less than one gram per square centimeter, the density of the water in which they float.
