Final answer:
The volume of the irregularly-shaped piece of copper is approximately 6.57 cm³.
Step-by-step explanation:
The density of a substance is defined as its mass divided by its volume. To find the volume of the irregularly-shaped piece of copper, we need to use the formula:
density = mass/volume
Given that the mass of the copper is 58.9 grams and the density is 8.96 g/cm³, we can rearrange the formula to solve for volume:
volume = mass/density
Substituting the given values into the formula, we get:
volume = 58.9 g / 8.96 g/cm³
Calculating this division, we find that the volume of the piece of copper is approximately 6.57 cm³.
