What tent size is big enough for 4 people?

Cori and three friends are going camping.

• They will share one tent, and they want a large enough tent to fit just their sleeping bags.
• Their sleeping bags are rectangular and all the same size.
• When purchasing a tent, the package is labeled with the dimensions of the rectangular base.

What size of tent should they buy? What could the dimensions of the rectangular base be? What could the area of the base be?

How could you get started?
• How much space would one sleeping bag require? What are the typical dimensions for a sleeping bag?
• How could you represent this situation?
• Why is it important that we consider the dimensions and not just the area of the tent base when making a recommendation?
• Use the internet to look at tents that are available for sale at stores near you. Would any of them meet the needs of Cori and her friends? Which one would you recommend they purchase?
• If a group of 30 friends were going camping, what size tents would you recommend they purchase? How many of them would they need?
