Please find the description below
Explanation:
The density of a substance refers to its mass per unit of its volume i.e the amount of a substance contained in a given volume. The density is calculated using the formula:
Density = mass/volume
Using this formula, with the known value for mass and volume of the boat, the density of the boat can be calculated.
An object will FLOAT on a liquid substance if its density is lower than that of the liquid while it will SINK if it has a higher density than that of the liquid.
In this case, with a known density of water, which is 1g/cm^3 or 1000kg/m^3,
a boat placed on water will FLOAT if its density is <1g/cm^3 (less than) while it will SINK if its density is >1g/cm^3 (greater than).
