Exodus 36:21

The length of a board was ten cubits, and the breadth of a board one cubit and a half.

Each board for the tabernacle measured ten cubits in length and one and a half cubits in breadth. The specification shows that the tabernacle was to be built with exactness, skill, and perfection in conformity to the pattern shown to Moses. That exact, skillful, and perfect workmanship stands as the example for every kind of work performed in God's service.
