That doesnt look like 500 gallons! Looks awesome though. Can you put something by it for a size reference?
but since the field I am studying for rely's heavily on math (doh) I've had to hone up some lol.Finding and average is quite easy though, but you have to know the measuremets.
Say you have a set of 6 different numbers (2, 23, 45, 15, 78, 45) you add those together (208) then divide by the amount of numbers you have (6), your average would be 34.67.You generally use this to find averages for business use (like sale trends, profit trends, ect.).
Although I'd agree with the tiles being about 12" square, spades are normally about that size and the tiles look the same size as the spade head thingy. Will look great when its finished
