How many squares are there formula?
So when we add (n-m) columns, total number of squares increased is (n-m)*m(m+1)/2. So total number of squares is m(m+1)(2m+1)/6 + (n-m)*m(m+1)/2. Using same logic we can prove when n <= m. Below is the implementation of above formula.

Square Grids Yield Square Number of Rectangles
Posted on January 17th, 2016 by kramer
Last week we explored the amazing pattern of squares withing square grids. The result is always a sum of square numbers such as 1 + 4 + 9 + 16 + 25 … in a 5×5 grid.
This week we continued this geometric exploration looking at the more challenging problem of how many rectangles. The first challenge was listing the different rectangle dimensions in a systematic order such as 1×1, 1×2, 1×3, 1×4, 1×5, 2×2, 2×3, 2×4, 2×5, 3×3, 3×4, 3×5, 4×4, 4×5, and 5×5 for a 5×5 grid. We discovered several different methods of counting rectrangles of various dimensions. Each of the square rectangles follow the same pattern as last week’s challenge so the 1×1 was 25 rectangles, the 2×2 was 16 rectangles, the 3×3 was 9 rectangles, the 4×4 was 4 rectangles, and the 5×5 was 1 rectangle. When counting the 1×2 rectangles, we can choose horizontal and count to 20; we simply double that number to address the vertical rectangles so we have a total of 40.
The number of rectangles in a 1×1 square grid was of course 1.
The number of rectangles in a 2×2 square grid was 9.
The number of rectangles in a 3×3 square grid was 36.
Some of the children were able to make a conjecture (educated guess) about how many rectangles there would be in a 4×4 square grid. The children noticed that each solution was a square number of 1×1, 3×3, and 6×6. Most students guessed that the 4×4 grid would have 81 or 100 rectangles (the actual solution was 100 or 10×10), and then solved the 4×4 grid. Next, they made a conjecture about the number of rectangles in a 5×5 square grid (the actual solution was 225 or 15×15). The children should be able to find the solution for the 6×6 and so on as long as they follow the sequence. Some of the students found that the sequence of square numbers were based on triangular number squares (1, 3, 6, 10, 15, 21, 28, 36 and so on).

Multiple-choice questions have a special grading rule determined by your instructor. Assume that your instructor has decided to grade these questions in the following way: If you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(n−1) of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.
If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question?

Are there too many squares in a 2 x 2 box? 3
Five … and I’m not sarcastic or stupid. Four are small and the outer one is five.
= 1 + (2×2)
= 1 + 4
= 5
Answer: 5 boxes.
Explanation:
2×2 squares In addition to one square, 2×2 squares have 4 other squares, for a total of 5 squares.
In a 2×2 box, 5 = 2 2 + 1 2 square.
In 3×3 square, 14 = 3 2 + 2 2 + 1 2 square
In 4×4 square, 30 = 4 2 + 3 2 + 2 2 + 1 2 square
Etc. is the formula.
The sxma squares in the nxn grid are n 2.

Just multiply 2 by 2.

Oh …
