My favorite approximation is: 355/113 (visualize 113355 split into two 113 355 and then do the division). The first 6 decimal places are the same.

3.141592920353982 = 355/113
vs
3.1415926535897931

Or (more for fun than any practical application) try (2143/22)^(1/4) =
3.14159265268.

Other approximations I have seen are root(10) and 3.142. This last
was especially popular at school, which for me was sufficiently long
ago to have used four figure log tables.

The Old Testament (1 Kings 7,23) says ... "And he made a molten sea,
ten cubits from the one brim to the other: it was round all about, and
his height was five cubits: and a line of thirty cubits did compass it
round about. ". So pi=3. End Of.

I think that particular author of that particular part of the bible just
used it to make the text appear older than it was at the time.

I don't believe that Neil was asking a serious question.

3 is the best integer approximation to pi. So the bibel is right.

There's nothing wrong with that value. The measurements were given
with one significant digit, so the ratio of the two measurements
should only have one significant digit.

I use cubits all the time. The distance from my elbow to my finger tips equals one cubit. When you don't have a proper measuring tape, it can be pretty accurate for comparing two measurements.
