Because it is not reasonable. But that's not to say that it's not bold, daring, and revolutionary thinking. Stick with it. That kind of thinking can get you anywhere these days...
There are 216 permutations of three dice. Of these, 206 have a sum that is less than 16, specifically, the permutations 466, 556, 565, 566, 646, 655, 656, 664, 665, and 666 have sums that are 16 or greater - all other permutations have sums that are less than 16. The probability, then, of rolling a sum less than 16 on three dice is 206 in 216, or about 0.9537.
No ! The 216 engine is longer !
216 is divisible by: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216.
220 inches is longer than 18 feet. There are 12 inches in a foot. This means that 18 feet is 18 * 12 inches, or 216 inches. 216 < 220.
Less than 15 cents.
18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216.
Is worth less than 50 cents.
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216
It is: 216
The biggest perfect cube that is smaller than 250, is 216.
72 yards = 72*3 = 216 feet. So you require a rectangle whose area is 206 sq feet and whose perimeter is 216 feet. Thus, if the sides are x and y, then xy = 206 and 2(x+y) = 216 ie x+y = 108 This gives rise to the quadratic: x2 - 108x + 206 = 0 and the solution gives the dimensions of the required rectangle as 1.94234 ft x 106.0577 ft. All this assumes, with no justification, that the required shape is a rectangle and not a circle or an irregular shape.
(216*36)+54 = 7830
