Adding different practice problems to your study routine for surface area and volume is very important for a few cool reasons!

1. Strengthening Your Knowledge: Working on different types of problems helps you really understand important formulas. For example, the surface area of a cube is $A = 6s^2$, and the volume of a cylinder is $V = \pi r^2 h$.

2. Building Critical Thinking Skills: When you try different kinds of problems, you learn to think outside the box and use what you've learned in many situations.

3. Getting Ready for Tests: Practicing various types of questions makes you feel more confident. This way, you can handle whatever the test asks you!

So, get excited—let's tackle those problems together! 🎉
