Question

how will we come to know the density without testing❓​

Answer 1

Answer:

We can pull out the density of an object by the formula :

$\sf{ \boxed{density \: = \sf{\frac{mass}{volume} }}}$

Explanation:

Density is the ratio of mass and volume. or its the amount of mass per unit volume. The different object has different density it is because density is the relation between mass and volume itself. The heavier objects have high density and lighter object have low density.

Answer 2

Answer:

density = mass / volume
