54 and How Many Squares Are in This Puzzle?

How many squares are in this puzzle? Finding that answer is too tedious for me to pursue. There is 1 square that is bigger than all the rest, 169 of the smallest size squares, and some different number between 1 and 169 for each size square in between. Solving the actual puzzle will actually be less work and more fun. The actual puzzle challenges you to write the numbers 1 through 12 in the top row and again in the first column so that the answers you write and the clues inside the puzzle work together as a multiplication table. Use logic to find the unique solution to the puzzle. 2014-04 Level 6 This week’s puzzles are available in an excel file here. If you have a spreadsheet program on your computer, you can access it. If you enable editing in excel, you can type your answers directly onto the puzzle, and you can also easily print the puzzles. Here are the factors from last week’s level 6 hook-shaped puzzle: 2014-03 Level 6 Answer Here is one way those factors can be found using logic. 2014-03 L-6 steps

54 is a composite number. 54 = 1 x 54, 2 x 27, 3 x 18, or 6 x 9. Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54. Prime factorization: 54 = 2 x 3 x 3 x 3, which can also be written 2 x 3³.

Sometimes 54 is a clue in the FIND THE FACTORS puzzles. Even though it has other factors, the only multiplication fact the puzzle uses is 6 x 9 = 54.

  1. If I understand the opening question correctly (the number of NxN squares that you can derive from the grid squares of the puzzle itself), it’s pretty simple; there’s 1 13×13, 4 12×12, 9 11×11, 16 10×10, etc., all the way up to 169 1×1. 819 in all.

  2. You make it sound so easy! I wasn’t aware there was an algorithm to find the answer, but I shouldn’t be surprised there is one. Thanks for enlightening me.
