Question

A wooden block measuring 40 cm x 10 cm x 5 cm has a mass 850 g. Find the density of the wood.

Answer 1

Answer:   0.425 g / cm³

Explanation:Given :

Mass m = 850 g

Dimension of block = 40 cm × 10 cm × 5 cm

Volume of block = 2000 cm³

We're asked to find density d :

We know :

Density = mass / volume

= > d = m / v

Putting values here we get :

= > d = 850 / 2000 g / cm³

= > d = 85 / 200 g / cm³

= > d = 0.425 g / cm³

Answer 2

Answer:

425 kgm‐³
