A cubical tank is filled with water to a level of 2 feet. If the water in the tank occupies 18 cubic feet, to what fraction of its capacity is the tank filled with water?

Volume of water in tank h*l*b = 18 sq ft ; h = 2 ; therefore l*b = 9 ; hence l = b = h= 3; total volume = l*b*h = 27 ; hence ration is 18/27 = 2/3 hence E)

Can you elaborate on the highlighted portion. How did you get that? _________________

Hi,

I have a doubt is the Question is it mentioned as tank is fully filled with water?

It mentioned as water is filled to level of 2 feet so dosen't it mean that water is not fully filled?

according to the question 18 ft is the height..the level to which water is filled in the tank..not the volume

a) 1/9 b) 2/9 c) 1/3 d) 1/2 e) 2/3

What is the source of this question?I am not able to solve it...Experts please help

It mentioned as water is filled to level of 2 feet so dosen't it mean that water is not fully filled?

And also Formula for cubical Tank volume is = a^3

Rectangular Tank Volume = l*b*h

Please clarify me.

Thanks in advance, Rrsnathan

Got this one

2*l*b=18 (As the tank is a cubical l=b=x) So 2*x^2=18 x^2=9, x=3

Fraction is: Volume of water filled/volume of tank =2x^2/x^3 (Substitute x=3) =2/3

volume is expressed in cubic feet. what is 18 feet here is unclear. _________________

Since its a cubical tank, l=b=h we know 2*l*b=18 so l*b=9 so l=b=9 also h=9 when tank is filled completely for completely filled tank l=b=h=3 volume=3*3*3=27

Considering a cuboid with height = 2 (which will be the height of water in the tank) and length and bredth same as that of the original tank. This cuboid's area is nothing but the volume of water which will be l*b*h = 18 which will be l*b = 9. Now since the original tank is a cube the length, bredth and height are all same thus we get l*b = l*l = 3 each and therefore the original cube's volume as 3*3*3 = 27.

Hope its clear now.
