Answer:
See below
Step-by-step explanation:
<u>Number of squares:</u>
- 1x1 squares = 8*8
- 2x2 squares = 7*7
- 3x3 squares = 6*6
- 4x4 squares = 5*5
- 5x5 squares = 4*4
- 6x6 squares = 3*3
- 7x7 squares = 2*2
- 8x8 square = 1
<u>Total number:</u>
- 8² + 7² + 6² + 5² + 4² + 3² + 2² + 1 =
- 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 =
