Question

The volume of the 40 gram of a solid is 15 centimetre cube. if the density of water is 1 grams per centimetre cube will the solid float or sink in water? state reason

Answer 1

Density of Solid = mass/Volume
= 40/15 = 2.66666667 g/cm³
Now density of solid is greater than the density of water ( 1g/cc )
=> Solid will sink !!
_____________
hope it helps !

Answer 2

We know that,

Density = Mass/ Volume

So the Density of the solid = 40/15

or, The density = 2.67g/cm^3

Given density of water is 1g/cm^3

We can see that the Density of Solid is greater than density of water (as 2.67>1)

The solid object will sink.

Hope it helps.
