My daughter was working on a math problem today. She initially got it wrong, and as I was helping her with it the second time, I came across something I thought was pretty cool.<\/p>\n
The problem called for her to calculate the perimeter of a rectangle. The rectangle had two sides that measured 16 units and two that measured eight units. The answer was 48, but the coolness lies in something further.<\/p>\n
If you add the two eight-unit sides, you get 16. Now you have a total of 3<\/strong> 16’s. The square root of 16 is 4, or 4<\/strong> x 4<\/strong> = 16.<\/p>\n
Now, if you multiply the 3<\/strong> by the first 4<\/strong>, you get 12. If you multiply that 12 by the second 4<\/strong>, you get, surprise, 48 (or 16 + 16 + 16).<\/p>\n
This works with any whole number that is a square. That number added three times (or multiplied by three) equals its square root multiplied by the product of its square root and three.<\/p>\n","protected":false},"excerpt":{"rendered":"
