TOO BIG OR TOO SMALL?

money in a suitcase

To put the question another way:

Will one million one dollar bills fit in a suitcase?

This book will help you answer the question. If you would like to try solving the problem on your own, don't go any farther in the book. If you get stuck, come back to the book.

Our three tutors, Pedro, Hali and Monty, will help by reminding you about some math you will need from earlier classes.

Pedro is the expert on finding area and volume.
Hali is the expert on decimals and fractions.
Monty is the expert on estimation.
