Calculate marble’s volume & density
Looking for:
volume, then density
Givens:
mass = 6 g , water displaced 30 to 32 mL
Relationships:
water displaced = marble volume, D = m/V
Solution:
32 mL – 30 mL = 2 mL
D = 6 g / 2 mL
= 3 g/mL

6. 2.4 How to solve design problems
Use what you know to design a solution that solves the problem.
Unlike “formula problems,” design problems have many correct solutions.
The solutions are only limited by your creativity, ingenuity, skill, and patience.

7. 2.4 How to solve design problems
What does your design need to accomplish?
What constraints do you have?
Think of an idea.
