# A Raft Of Wood (Density 600 G/M3) Of Mass 120 Kg Floats In Water. How Much Weight Can Be Put On The Raft To Make It Just Sink?

Given:

Density = $$600 g/m^{3}$$

Mass of a raft of wood = 120 kg

The mass of water displaced =

$$\frac{120}{600} * 1000$$ $$\Rightarrow$$ 0.2 * 1000

$$\Rightarrow$$ 200kg

The mass of a raft of wood = 120 kg

Therefore, the total weight reqiored to amke the raft sink is:

$$\Rightarrow$$ 200 – 120 = 80 kg.
