How can I solve this problem?

Hello, someone can explain how to solve this?

A silver cube has edge lengths of 5cm each.
A stamp mark '800' indicates that the cube is made of 800/1000 pure silver. Assume that
silver has a density of 10.5 g / cm3 and a price of 0.68 €/g.
Calculate the value of the silver portion.

Thank You

What is the volume of the cube?

Assuming that the alloying % in this problem refers to "volume" (however, the alloying % generally refers to "mass")

What is the volume of silver in that cube?

From above volume and given density - What is the mass of the silver in that cube?
