Question

Lenny accidentally drops his matchbox car into a graduated cylinder. If the car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D = m/v

Answer 1

D = mass / volume
The volums is 46-41 = 5 ml
so D = 10/5 = 2 g / ml
