Question

Miguel gets mad at Greta and throws her back pack in the pool.Miguel says it’s okay,because the mass of the back pack is less than the volume.Why is it important?

Answer 1

Her back pack will float because its density is less than the density of the water.

Step-by-step explanation:

Because if the mass of the back pack is less than its volume, the density of the back pack will be less than 1 (one).

The formula for density is:
`density=(mass)/(volume)`, therefore if the mass is smaller than the volume (denominator is larger than the numerator for the density) the quotient will render a number smaller than one.

That means that the object will float in a pool filled with water because the density of the water is one. The object with lesser density will float .
