So, if bees built triangular cells, they would have to use 25% more wax to match the hexagon’s surface area. If you want to build a triangle with a surface area of 64.95 cm2, it will have a perimeter of 37.75 cm, 25% longer than that of a hexagon.
It will have 10 cm sides and a surface area of only 43.3 cm2. Let’s do the same to a triangle with a perimeter of 30 cm. For our hexagon, we have the following formula: (3 × √3 × 25) ÷ 2 = 64.95 cm2. The hexagon’s surface area formula is: (3 × √3 × S2) ÷ 2, where “S” is the length of the hexagon’s side. So, the hexagon with 5-cm sides has a perimeter of 30 cm. The formula of a perimeter is the sum of all sides: 5 x 6 = 30. Let’s assume the hexagon’s sides are 5 cm long. The hexagon has the smallest perimeter for a given surface area. Then, why not triangle or square cells? They won’t be efficient either.Ī lot of math happens in those hexagon cells. The question is: Why not round honeycombs? Round cells will not fit well because they will leave huge gaps. They never use any shape but a hexagon for their hives. #2 Why Do Bees Construct Hexagons in Their Hives?īees seem to be some of the most hardworking living beings, but these little buzzy things are also practical about space allocation. As a result, the cylindrical bag will fit more popcorn, which means you will get more snacks for the same price. The cone’s volume is always 1/3 of the cylinder’s. But mathematicians know you will pay a higher price for a coned bag. Which one should you choose? At first sight, there is no difference. You can get any for $5, and both look equally big. But then you step to the popcorn stand and see two popcorn bags, a coned one and a cylindrical one. You go to the cinema anticipating getting a big popcorn bag to make your mouth busy for the rest of the movie. Check these real-world math problems: #1 Which Popcorn Container Is Better? Teachers often bring real-life situations to the classrooms to make math more sensible and contextualized. Math for Kids Is Your Child Struggling With Math?ġ:1 Online Math Tutoring Let’s start learning Math! Math in the Real World: 4 Examples Everything from architecture and machinery to medicine and iPads exist thanks to calculations. However, if you look at math on a broader scale, you will notice that human civilization as we know it appeared thanks to ancient Greek mathematics. It also helps your brain recruit certain areas better. Math develops logical thinking and spatial skills. Going shopping, cooking, working – these and many other activities touch on numerical calculations.īeing fluent in math means being successful in thousands of activities. After all, most of us leave all those equations behind after we graduate from school.īut the truth is that we use math concepts in our daily lives without realizing it. How Is Math Used in the Real World?įor many people, math doesn’t have any practical application. Teaching children math through real-life world problems is a whole different story.
Well, it does happen, but the problem is that sometimes schools can’t deliver this knowledge in the right way. No wonder many children ask themselves: “How will those abstract equations help me in life? What’s the point of practicing ‘John bought 45 watermelons’ equations all the time if nothing of this happens in real life?”
