When it comes to science and mathematics, the Bible tends to cut a lot of corners; not surprising given the time it was written and the authors themselves. However, if it is the perfect word of God, it should be more accurate than this. Witness Pi, which most kids with some high school education can tell you is 3.14159. The truly underachivers in the class will likely still get it to two decimal places, namely 3.14.
Looking in the Bible, we discover that the value of Pi is 3, not 3.14 as those heathen non-believer mathematicians would have you believe. Three!
1 Kings 7:23-26
King James Version (KJV)
23 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.
24 And under the brim of it round about there were knops compassing it, ten in a cubit, compassing the sea round about: the knops were cast in two rows, when it was cast.
25 It stood upon twelve oxen, three looking toward the north, and three looking toward the west, and three looking toward the south, and three looking toward the east: and the sea was set above upon them, and all their hinder parts were inward.
26 And it was an hand breadth thick, and the brim thereof was wrought like the brim of a cup, with flowers of lilies: it contained two thousand baths.
