The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
20 squares x 20 squares = 400 squares
Yes. And here is an example: Draw a 6*6 array, put the two 3*3 squares anywhere within that aray so that they don't overlap. That leaves 18 square units - each one to be occupied by one of 18 unit squares. 2 large (3*3) squares plus 18 small (1*1) squares makes 20 squares Total area = 6*6 square array DONE!

6... with a remainder of 6 1x1 squares.
2,000 square feet is 20 squares.

If you don't specify the size of the squares, we can't give an accurate answer. There are 400 one-unit squares and 200 two-unit squares and 4 ten-unit squares and so on.

20 in x 20 in = 400 in2 = 2,777778 foot2120/2,78 = 43 squares
In a 4 by 3 grid, there are a total of 20 squares. To calculate this, you can start by counting the individual squares of each size within the grid. There are 12 one-by-one squares, 6 two-by-two squares, and 2 three-by-three squares. Adding these together gives a total of 20 squares in a 4 by 3 grid.
To find the perfect squares between 20 and 150, we need to determine the perfect squares less than 20 and the perfect squares greater than 150. The perfect squares less than 20 are 1, 4, 9, and 16. The perfect squares greater than 150 are 169 and 196. Therefore, there are 5 perfect squares between 20 and 150: 25, 36, 49, 64, and 81.
