Question

the mass of a block made of a certain material is 13.5 kg and its volume is 15×10^-3 m^3 .Will the block float or sink in water?

Answer 1

Hii There!!!


Given, mass = 13.5 kg

Volume = 15×10^-3 m^3


Since, we know that Density = mass / volume

=> 13.5 kg / 15 × 10^-3

= 900 kg/m^3

Density of water is 1000 kg/m³. 

As , its density is lower than the density of water, it will float in water.



======================

Hope it helps

Answer 2

Given
m = 13.5 kg,
V = 1.5 x 10^-3 m^3
Therefore,
Density = Mass/ Volume
= 13.5/15 x 10^-3 = 900 kg m^-3
As it is less than 1000 kg m^-3 the block will float.


can u mark my answer as branliest too
