Grid measurements

Check my addition

horizontally:
Two 3p0 margins top, bottom (2 x 3p0)
Two 1p9 gutters between the columns (2 x 1p9)
Three 7p10 wide columns (3 x 7p10)
= 33p0 page width.

vertically:
top and bottom margins (2 x 3p0)
45p0 column depth (1 x 45p0)
= 51p0 page height.

So how many lines of type do you get in each column?
If unsure of this or how to set up your grid, email me.
