How many blocks of 450mm length and 225mm height would be needed for a wall of 170square meter?

Area of each block = 450 mm x 225 mm = 0.45 m x 0.225 m = 0.10125 m2
Area to be covere = 170 m2
So, minimum number of blocks required = 170/0.10125 = 1679.01 = 1680.
However, this assumes that there is virtuall no wastage and, in real life, you should allow 5-7% extra.

How many blocks wouLd be needed for 50000 sq ft?
The only information you've given is that there is a surface with an area of 50,000 ft2. We need to know the size of the blocks to know how many are going to fit. If we assume for the blocks length L and width W, then all we can do for now is assume this formula: 50,000 ft2/L*W = number of the blocks needed

How do you figure up how many cinder blocks you need?
Calculate the exterior face area of he wall you want to build and the face area of the side of the cinder block (add about 1/2 inch to length and 12 inch to width for mortar thickness). Divide the wall area by the block area This is the number of blocks you require. This is how I figure out how many blocks you will need: First measure the length of walls for the blocks in feet. Second divide that number by 4 then multiply the total by 3. That will give you total blocks needed for one course of blocks.
