# Word Problem Wednesday: Campfires, Marshmallows, and Middle-School Math

Aug 1, 2018 | Diamond Bar

One of our favorite things to do during the summer is have a campfire! What goes hand in hand with a campfire? Smores! Did you know that the crucial ingredient in smores (marshmallows) are perfect for practicing math? Yes, you read that right, marshmallows and math skills go hand in hand. This week’s word problem challenge provides a fun and foodie opportunity to practice volume, percent, multiplication, and other middle school math skills.

Question: An unroasted marshmallow has a volume of 0.25π cubic inches. After Andrew roasts the marshmallow over a campfire, its volume is 150% its original volume. What is the post-roast volume of the marshmallow?

Go ahead and give it a try. Take your time, and when you’re ready, check below for the solution.

Solution: To find 150% of 0.25π, we can multiply the 1.5 by 0.25 and then by π: 1.5 multiplied by 0.25 is 0.375, and 0.375 multiplied by π is 0.375π. So, the volume of the roasted marshmallow is 0.375π cubic inches.
