A cubic catalyst nanoparticle has a side length of 15 nm15\text{ nm}15 nm, as shown in the diagram below.

A 3D line drawing of a cubic nanoparticle with a side length of 15 nm

Calculate:

a.

The total surface area of the cubic nanoparticle.

[2]
b.

The volume of the cubic nanoparticle.

[1]
c.

The simplest whole-number ratio of surface area:volume\text{surface area} : \text{volume}surface area:volume for the cubic nanoparticle.

Use the equation: surface area of cubic nanoparticle=6×surface area of one face\text{surface area of cubic nanoparticle} = 6 \times \text{surface area of one face}surface area of cubic nanoparticle=6×surface area of one face
