Question

A piece of wood of mass 150 grams has a volume of 200 cm cube find the density of wood in S.I. unit

Answer 1

Answer: 0.75 g/cm3

Explanation:

Formula for finding density: $\frac{Mass}{Volume}$

So by replacing the values we get

$\frac{150}{200}$  which is equal to $\frac{3}{4}$

$\frac{3}{4}$ is the same as 0.75 g/cm3

(Hope you understand! <3)

Answer 2

Explanation:

Mass=150gms

= 150*10^-3 kg

volume=200 cm

=200*10^-6 m^3

density=Mass/vol

=15*10^-2/2*10^-4

=750 kg/m^3
