It’s the first Wednesday of June which means it’s time for our monthly linky – Math IS Real Life!! If you want to see how the linky works, or just want other real world math ideas, check out our Pinterest Board of all the posts so that you can look back and find some great ideas and REAL pictures to use in your classroom!

A monthly REAL WORLD math blog link-up hosted by MissMathDork,
It’s summer here at the MathDork houses which means it’s time to get some house projects done! Once I begin a project, I don’t really like to stop until it’s complete…. so I needed to stop by the grocery store to pick up some fast, easy lunches to help minimize the downtime while in project-mode.
One of my go-to lunches are personal pizzas. Quick. Easy to eat. Clean up is super easy. Delicious.
When I reached in to grab my usual, I noticed the package had changed…. drastically.
I also noticed the label in the corner “Same amount of pizza, now less packaging”. For some reason I took that label as a challenge — yes, yes, I *am* that person….
The pizzas just didn’t seem to be the same size, albeit the packaging was definitely less. The round pizza has both cardboard box packaging and a plastic shrink wrap around it. The rectangular pizza only had a plastic packaging.
The round pizza had a diameter of approximately 8 inches.
Area of a circle = pi * r * r
Area of the circular pizza = pi * 4 inches * 4 inches
Area of the circular pizza = 16 pi square inches
Area of the circular pizza = approximately 50.264 square inches
The rectangular pizza had a height of approximately 7 inches…
… and a width of approximately 8 inches.
Area of a rectangle = height * width
Area of the rectangular pizza = 7 inches * 8 inches
Area of the rectangular pizza =approximately 56 square inches
The area of the circular pizza is approximately 50.264 square inches
The area of the rectangular pizza is approximately 56 square inches.
WOW! Not only did the company SAVE money and trash by having LESS packaging, they ended up giving me MORE pizza! I’ll be quite honest, I was expecting the round pizza to be larger, even if only slightly! Kudos to the company for now short-changing the pizza… though, I bet them mentioning the pizza being a bit bigger would be good for marketing!
Edit: I went back and looked and the weights of both pizzas are the same. I then checked the thickness of the pizza and the rectangular pizza is slightly thinner. It appears that the AREA of the rectangular pizza is larger, but not the thickness 🙂
