Question

a rectangular water tank is 7 of 6 m contains water upto depth of 5m how many litres of water is there in the tank

Answer 1

Hi Harsh,

Let us first find the amount of water present in the tank (we need to find the volume upto the depth level of 5m=Height or Depth)
 
Length * Breadth * Depth = Volume of the tank (filled volume)
so here we have : 7m * 6m * 5m = 210 cubic metres

Now, we need to convert the units in litres.(important step)
Cubic metres into litres : 1 cubic metre = 10000 Litres
Therefore,
the answer is 210*10000L = 2100000 Litres

Hope it helped you.
Please let me know if any further doubt.
Cheers !!!
