Question

A boy made a model ship with a mass of 1.1 kg and a volume of 900 cm³. Will it float on water? ( density of water is 1000 kg/m³)

Answer 1

Volume of ship = 900 cm³ = 9 m³

Density of ship = 1.1 ÷ 9 = 0.123 kg / m³

since the density of ship is less than water therefore it will float

Answer 2

Answer:

I say that the answer to this is pretty simple. not has hard as it seems. really easy. what you have to do is just

as we see the density of water is given in m^3, we shall first convert the volume in cm to m. so it will surely be 900/100 as 100 cm is 1 m. Volume now 9m^3

Finally we put in the values to find the density of the ship as we need to see whether it will float or not.

so, density = mass/volume

= 1.1 / 9

so density of the ship is 0.123 kg which is so much more lower than the density of water. Hence it will float on water
