Answer:
volume of the mixture is (0.575+0.300)-----> 0.875 m³
Explanation:
we know that
density=mass/volume--------> volume=mass/density
step 1
find the volume of water
mass=575 kg
density of water=1000 kg/m³
volume of water=mass/density-----> 575/1000----> 0.575 m³
step 2
find the volume of ice
mass=275 kg
density of ice=916 kg/m³
volume of ice=mass/density-----> 275/916----> 0.300... m³
the volume of water is 0.575³
the volume of ice is 0.300.. m³
volume of the mixture is (0.575+0.300)-----> 0.875 m³
