How many concrete 12x12 blocks do i need to make a 12x12 patio
Uhm.... The block AND the patio measure 12x12? In that case you only need one....
132 blocks depending on whether you will have grout.
The typical answer would be 144. You must also consider unforeseen conditions.Example: 1. Is the ground level/ I leveled? If unlevel then blocks would be needed to use under the patio to level it depending on how steep the grade is.2. Replacements for damaged blocks.
well if they both measure 12x12 then one but if the block is 12x12feet and the patio needs to be 12x12 yards then you have to do the math
12x12 = 144!!! :)
Ahhh... 12x12=144 or 12 dozen also known as "a gross".You would order a gross of 12x12 blocks, but it always good to get a few more then you actually need.
Units matter. If you are using 12"x12" block and desire a 12'x12' patio, then 144 blocks are required. Other units give other results.
