Answer 2

Answer:

The density of wooden block is $0.8 gcm^{-3}$  and $7800 kgm^{-3}$.

Explanation:

• A mass is defined as the resistance of the body when a matter that will offer to change the speed position which acts upon the application of the force.

The SI unit of mass is kilogram.

• A volume is defined as the scalar quantity that expresses the three dimensional space which is attached to a closed surface.

Volume has a SI Unit called as cubic meter.

Given that:

mass of a wooden block =200 g

volume = $250 cm^{3}$

To find:

The density of wooden block in

(a) $gcm^{-3}$  (b) $kgm^{-3}$

Solution:

1) By applying the formula of density.

Density = mass / volume

= $200/250$

= $0.8 gcm^{-3}$

2) we are going to find the density of wooden block in kgm-3

Density = $1000 * 7.8 kgm^{-3}$

= $7800 kgm^{-3}$
