First of all, I calculated that a perfectly square acre could contain
a maximum of 17,528 8"x8"x16" concrete blocks, allowing a 3-foot space
in between for a mower. At $1.20 per block, it would cost $21,033.60
to purchase concrete blocks for one square acre.


Kevin, that number of 17,000 sounds a bit too high comparing my own
acre which has block on it. Acre is about 44,000 sq ft and consider a
block takes up about 1 sq ft I think that 10,000 block with 3 ft strips
of weeds/grasses to mow for fertilizer is more akin to my acre test
plot.
