A nanoparticle of a metal oxide has a surface area of 15,000 nm215,000\text{ nm}^215,000 nm2 and a volume of 12,500 nm312,500\text{ nm}^312,500 nm3.
Calculate the surface area to volume ratio of this nanoparticle.
Give your answer in the form x:1x : 1x:1.
surface area to volume ratio = ............ : 1
