If you put a coin on a square than 2 coins on the next square than 4 than 8 than 16....althe way to the 64th square how many coins will you have and what is a formula for finding any number of squares?

You'll need 2 to the power of 63 coins for the last square. This number is so large that there isn't enough room on the website. The total number of coins is (2 to the power of 64) -1, which is almost twice as many For a board of N squares you need (2 to the power N) - 1 coins. As an illustration, for a 2 x 2 (or 1 x 4) board you would need 1 + 2 + 4 + 8 coins, ie 15 which is (2 to the power 4) - 1.

What is the formula to find the number of squares on a chessboard?
The square of the number of tiles on each row or column. Generally a chess board has 64 squares. This answer given above by one of our friends is true only incase of squares of same size. But as we consider all possible squares of different sizes, then it will be calcualted using the formula, 12+22+32+42+52+62+72+82
Is there a formula for finding the measure of interior angle of a regular polygon?
Yes and it is: sum of interior angles/number of sides
How many Squares are in a 7 by 7 grid?
There are 49 of the smallest squares. However, any grid forms "squares" that consist of more than one of the smallest squares. For example, there are four different 6x6 squares that each include 36 of the small squares, nine different 5x5 squares, sixteen 4x4 squares, twenty-five 3 x 3 squares, and thirty-six different squares that contain 4 of the small squares. One could therefore discern 140 distinct "squares." The number can be calculated from the formula [(n)(n+1)(2n+1)] / 6 where n is the grid size.
What is the number of distinguishable permutations?
The formula for finding the number of distinguishable permutations is: N! -------------------- (n1!)(n2!)...(nk!) where N is the amount of objects, k of which are unique.

1/2 x (a+b) x hA =is the average number of parallel sidesB = is the distance between themh=is the height
Ho do you prove the formula for the area of a rectangle?
Use squares and try it out for yourself. Get a number of squares and make a rectangle 3 squares long by 4 squares wide. Count the squares. You should have 12 squares (or 3*4). That's the best way I know to prove the formula.

Sum of N2 for N=1 to X, and X is the number of squares across the top or side on the large square.
How many squares does a 7 by 7 grid have?
7 x 7 = 49 of the smallest squares if there are 7 squares on each side. The total number of "squares" of any size (1 to 49 of the smallest squares) is 140. The number can be calculated from the formula [(n)(n+1)(2n+1)] / 6 where n is the grid size.
What is the formula for finding the number of hours in any number of days?
multiply number of days by 24. so the formula would be '''hours = days x 24'''
