:
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.
