Question

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.

Answer 1

you need to raise the water by 4 cm. That would be a volume of 30x20x4 cm^3

But, the 4 cm of the block displace water, so you need to subtract 10x10x4 cm^3 from that total.

Then convert cm^3 to liters.

Answer 2

1.4 litres

Answer 3

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)

Answer 4

How is the volume of tank 30×20×10? The dimensions in question are 30×20×12...

Answer 5

Thanks

Answer 6

Your are wrong bakayaro

Answer 7

Intelligent
But the height of the tank taken in the beginning is inappropriate

Answer 8

I think you should have said in the beginning
Assuming that the cube is fully immersed the volume would have been 2030*20*10

Answer 9

Sorry 30

Answer 10

Oh and in the end it has to be 5000-3600=1400
Not 6000

Answer 11

Your ans is wrong correct answer is 2.4l
