Answer:
287cm^3
Explanation:
Given data
Density of aluminium= 2.7g/cm^3
mass of aluminium= 775g
The volume occupied is given as
we know that
density= mass/volume
volume= mass/density
volume= 775/2.7
volume= 287 cm^3
Now based on Archimedes principle, which states that when a body is totally or partially submerged in a fluid it experiences an upthrust which is equal to the volume of the mass displaced
Therefore, the volume of oil displaced is 287cm^3
