Answer:
The density of the stone is 6 g/cm³
Explanation:
The rule of denisty is d = M ÷ V, where
Let us use this rule to solve the question
∵ The volume of the stone is 30 cm³
∴ V = 30 cm³
∵ The mass of the stone is 180 grams
∴ M = 180 g
→ Substitute them in the rule above to find d
∵ d = 180 ÷ 30
∴ d = 6 g/cm³
∴ The density of the stone is 6 g/cm³
