# When a Golf Ball is Lowered into a Measuring Cylinder Containing Water, the Water Level Rises by 30 Cm3 When the Ball is Completely Submerged. If the Mass of Ball in Air is 33 G, Find Its Density. - Science

Short Note

When a golf ball is lowered into a measuring cylinder containing water, the water level rises by 30 cm3 when the ball is completely submerged. If the mass of ball in air is 33 g, find its density.

#### Solution

ρ (density of golf ball) = ?
V (volume of steel piece) = 30 cm3
m (mass of steel piece) = 33 g
ρ = m/V
= 33/30
ρ = 1.1  "g/cm"^3

Ans: Density of the golf ball = 1.1 g/cm3.
