How it works
To measure, lay same-size blocks end to end with no gaps.
The number of blocks is how long it is.
Blocks must all be the same size, and start at the edge.
Worked examples
Count the blocks
- A rope has 6 blocks laid along it.
- Count them: 1, 2, 3, 4, 5, 6.
- The rope is 6 blocks long.
Start at the edge
- Put the first block at the start of the rope.
- Lay the rest with no gaps.
- Then count them all.
A fair measure
- Some blocks have gaps between them.
- Gaps make the count wrong.
- Lay them end to end with no gaps.
