You need to convert your measurements into metric, then calculate the total square metreage.
Next, calculate the length of the perimeter and multiply by 0.1 to determine how many square metres of charcoal block would be needed for your edge course. (Multiply by 0.2 if using the bklocks at 200mm width)
Subtract the quantity of perimeter blocks from the total to determine the quantity of body blocks.
Remember to allow at least 5% extra for wastage, better to round up to nearest quarterpack.
Or pay somoene like me to work it all out for you!
