The overall cost basically depends upon the size of the swimming pool being considered.Here, I am considering a standard swimming pool of the following dimensions : 25 metres x 10 metres x 2 metres.So, from the the above dimensions, volume can be calculated as 25 x 10 x 2 = 375 cubic metres.Considering french fry as a cuboid, size would be 5.2 cm x 1.2 cm x 0.7 cm = 0.0000043 cubic metres.Assume the Cost of one french fry to be around 1.2 u20b9.Total number of french fries = 375 / 0.0000043 = 87209302Total cost would come be = 87209302 x 1.2u20b9 = 104,651,162u20b9 appx.Assuming french fries can be packed with no gap between them.PS : I have considered that french fries were directly ordered from McDonaldu2019s. It isnu2019t a bad idea if you are a millionaire.
