A stick of butter has a volume of 120cmcubed and a mass of 110g. Explain reasoning for each step

A.What is the volume of 1g of butter?
B. What is the volume of 6g of butter?
C.What is the mass of 50cmcubed of butter?
QUESTION 2
the density of silver is 10.5g/cmcubed
A. What is the mass of 7cmcubed of silver
B. What is the volume of 64g of silver
C. How many 1cmcubed pieces of silver must be combined to have a total mass of 64g
D. How are questions B and C related?

Question 3
One cubic centimeter of copper has a mass of 8.9G What is the volume of a piece of copper with a mass of 1.23 KG?

Question 4
Suppose we have a piece of lead with a mass of 70g. How much will the volume of lead increase if we add 30g more lead to this piece? Lead has a density of 11.3g/cmcubed

Answer 1

This isn't "physics expert" material. It's very simple.
density = mass/volume
volume = mass/density
mass = volume * density
Figure out which equation to apply. In questions 1 and 3, first get the density, then you can answer the question(s). In questions 2 and 4 you're given the density.
