Estimate brick, block, pavers 

Did you multiply it by 2 for some reason the 200

For a paver you need the width and length of the paver. Take the area needed to be covered and divide by the area of one paver. I use square feet.

Yeah I saw that too where did 400 come from

@@crowdrunner1973 that was the area for the block estimate

Sorry about that, sometimes I have to much going on in my head and make a mistake, I'm not perfect but I try.

Thanks for the advise I was wondering how he got the 1428

I have videos on estimating mortar for brick and block
