How will you expand the swimming pool 4 times more without removing the tress? It is like this na? :■: Ans: 1. Remove All Water. 2. Measure height of Swimming pool. 3. Now dig the swimming pool further down 3 times the actual height. 4. i.e if original height was 10m then after digging further new height will be 40m, i.e. Swimming pool gets expand 4 times the original one but at downword direction Regards Nivrutti

Re: How will you expand the swimming pool 4 times more Hi Mallesh, You have mentioned a square shaped swimming pool. We can make the the swimming pool 4 times by extending each of the lines of the square thrice. Is it the right answer? Thanks, Kris

Re: How will you expand the swimming pool 4 times more It is very simple we have trees only in corners. And it is not given that the final pool must be square shaped so will extent the pool as a 4m x 1m pool. Where there is no need to remove trees but we can't have all the trees in corner (at max only two trees can be in corner __________________ Cheers, :) James:)

Re: How will you expand the swimming pool 4 times more hi, take a = 1 m as the side of the squre. now the area of the existing pool is 1sq.mt. to get the pool 4times more, add an equilateral traingle each side of the square, now the trees come in the middle of the sides. length of a side now = 2 mts. area = 4 sq. mts. bye.

Its immposible to make it 4 times!!!!!!!!!! question it self is wrong Last edited by muralichmk : 04-19-2008 at 12:55 PM.
