The answers will depend on how large the image of the hand print is on your whiteboard. Answers can be generated based on the actual length of the handprint (tip of middle finger to the opposite edge of the print):

Length of hand on your whiteboard: cm

Here are the estimates of the size of the wookiee:

• Hand length:
• Height:
• Weight:
• Shoe length:
• Amount of fluid drunk per day:

The estimates are based on the following statistics of an average man:

• Average man's hand length: 18cm
• Average man's height 175cm
• Average man's weight 80kg
• Average man's shoe length 30cm
• Amount of fluid drunk per day: 2 litres

Hmmm! How did he get into your classroom?

Note to teacher: This diagram might help explain why a 2 fold increase in dimensions leads to an 8 fold increase in volume.
