I have a chemistry question

[Monysa Adhikary]

i have a chem problem,plz any1 help me out

Assume that a beach is made of identical grains of sand-each a cube of side 1 mm..assume also that these r packed tidily with no wasted space..What volume of sand(cubic metre) would contain the same no. of grains ass there r molecules in 1 drop(o.o5 cm^3) of water?

[{H=1; O=16}: density of water=1 gm/cm^3] """""plz send me ur process n answer"""

Formula of the sand molecule? Moles of Water?

I am not sure if I am wrong, but I think there is too little information to answer the question? Was this an actual question, in an actual paper? I think to get the answer you need 2 more things, the density and the formula of sand...
