a rectangular tank
30cm×20cm×12cm contains water to a depth of
6 cm.A metal cube of side 10 cm is placed in
the tank with one face resting on the bottom of
the tank.find the volume of the water in the litre must be poured in the tank so that the metal cube is just submerged in the water.
Volume of tank=30×20×10=6000 cc
Volume of cube=10^3=1000 cc
If the cube is fully immersed,then volume of water=6000-1000=5000 cc
Base area of tank=30×20=600 cc
When tank was filled with water at depth 6cm, then volume of water
=600×6=3600 cc
Therefore,Volume of water that must be poured in tank so that metal cube is just submerged in water =6000-3600
=1400cc
=1.4 litres. (1000cc=1litre)
1.4 litres
How is the volume of tank 30×20×10? The dimensions in question are 30×20×12...
Oh and in the end it has to be 5000-3600=1400
Not 6000
Intelligent
But the height of the tank taken in the beginning is inappropriate
I think you should have said in the beginning
Assuming that the cube is fully immersed the volume would have been 2030*20*10
Sorry 30
