Question 3

A researcher has a sample made of identical cubic ceramic particles. Each edge of a particle is 1 × 10-8 m long. The combined surface area of all the particles is 1.5×1017 nm21.5 \times 10^{17}\ \text{nm}^21.5×1017 nm2. All six faces of every particle are exposed.

What is the total volume of the ceramic particles?
