## Applet explorations

**1)**This is based on similar foundations to the previous activity. Again, we are looking to minimise the surface area for a given (constant) volume. Suggest an area where this particular problem might be useful to solve.

**2)**Play around with the applet to get a feel for the problem geometrically. What is the minimum possible surface area for the baking tin? For what approximate values does this occur?

**3)**Develop an argument algebraically to verify this result, following similar methods to the previous activity.

**Summarise any key points at the bottom of the page.**

## Applet conclusions

Note any key points from this activity. How can this applet be used to develop our understanding of calculus?
