Question

A sugar cube has a volume of 0.216 cubic inches. What is the length of each edge?

Answer 1

Each edge measures approximately `0.465` inches.

Explanation:

Since it's a cube, its volume `V` can be expressed as a function of the edge `l` follows: `V=l^3`.

Now we want to find `l` such that `l^3=V=0.216` cubic inches. This means that `l=root(3)V=root(3)0.216 approx 0.465` inches.
