A cubic nanoparticle has a side length of 5 nm5\text{ nm}5 nm, as shown in the diagram below.

A 3D line drawing of a cube representing a nanoparticle. Labels on the edges indicate a width of 5 nm, a depth of 5 nm, and a height of 5 nm.

Calculate:

a.

The 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
