What is 8 × 8?
8 × 8 = 64. This is one of the most commonly looked-up multiplication facts. You'll encounter 8×8 in geometry (an 8-foot square room has 64 sq ft of floor space), chessboards (an 8×8 grid has 64 squares), and basic arithmetic.
It's also written as 8² (8 squared), since squaring a number means multiplying it by itself.
8×8 in Real Life
- Chess/checkerboard: 8 rows × 8 columns = 64 squares
- Room size: An 8 ft × 8 ft room = 64 square feet
- Tile count: An 8×8 tile grid needs 64 tiles
- Computer storage: A byte has 8 bits — 8×8 = 64 bits in 8 bytes
- Rubik's-style puzzles: Some larger cubes use 8×8 face layouts
Frequently Asked Questions
8 times 8 equals 64. Written as: 8 × 8 = 64. Also expressed as 8² = 64 (8 squared).
8 squared (8²) = 8 × 8 = 64. Squaring a number means multiplying it by itself once.

The area of an 8×8 square is 64 square units. If the sides are in feet, the area is 64 sq ft. If in meters, 64 m².
Patterns that make the 8 times table easy
- Double three times. Because 8 = 2 × 2 × 2, multiplying by 8 is the same as doubling three times. For 8 × 7: 7 → 14 → 28 → 56.
- Ten times minus two times. 8 × n = 10n − 2n. For 8 × 9: 90 − 18 = 72.
- The last digits repeat. Multiples of 8 always end in 8, 6, 4, 2, 0 in that order: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80.
Why 7 × 9 is one less than 8 × 8
Numbers the same distance either side of 8 multiply to one less than 64: 7 × 9 = 63, and 6 × 10 = 60, which is four less. This is the difference of squares, (8 − a)(8 + a) = 64 − a², and it works around any number. It is a quick way to multiply pairs like 19 × 21 = 400 − 1 = 399.
