ANSWER
0.02 m³
Step-by-step explanation
By the Archimedes' Principle, the weight of a floating object is equal to the weight of the water displaced by the object,

This is,

We know that the weight of the canoe is 200N, so there is no need to find its mass. Also, the mass is the product of the density and the volume,

The density of water is 1000 kg/m³, the acceleration due to gravity g is 9.8m/s² and the weight of the canoe is 200N. Solve for the volume of water,
![V_(water)=(W_(canoe))/(\delta_(water)\cdot g)=\frac{200N}{1000\operatorname{kg}/m^3\cdot9.8m/s^2}=0.02m^3]()
Hence, the volume of water displaced by the canoe is 0.02m³.
