The diagram below represents a cubic nanoparticle of titanium dioxide.

A cubic nanoparticle with all three dimensions—width, height, and depth—equal to 3 nm

The volume of this cubic nanoparticle is 27 nm327\text{ nm}^327 nm3.

Calculate:

a.

The total surface area of the cubic nanoparticle, using the equation:

surface area=6×surface area of one face \text{surface area} = 6 \times \text{surface area of one face} surface area=6×surface area of one face
[2]
b.

The simplest whole-number ratio of surface area:volume\text{surface area} : \text{volume}surface area:volume for this cubic nanoparticle, written in the form X:1X : 1X:1.
