How do i work out the number of blocks needed to build a garage?

Question

the garage is 7.6 metres square with a side wall height of 2.8 metres and is cavity wall construction

Answer 1

what are the sizes of the blocks in metric? In inches and feet it takes 3 blocks in length(16inches) to equal 4 feet, and in height (8") 3 courses to equal 2 feet high.

Answer 2

work out how many sq meters there is, and for one single skin of block work there is 10 blocks per sq meter

Answer 3

Try this calculator

Good Luck

Answer 4

1.6 blocks per sq. ft.

Answer 5

concrete block is 16" wide. take the measurement of the perimeter of the garage, convert it into inches and divide by 16, also figure in the heigth, each block is 8" tall, so 24'' high would be three block high, take your first measurement and multiply by three. I'm not very familiar with the metric system, but if you convert my measurements to metric you will know...

Answer 6

Calculate area of 1 block (nominally 0.450 x 0.225) which gives 10 blocks per metre as near as makes no odds. Accordingly you would be looking at approx 213 for your job, but you should allow some for wastage as you 'll have to have some cuts, and you will probably have a cut row at the top. (say 230). Double this for a cavity wall - so 460 ish. Allow more for foundations if not included in your measurements.

That said you usually buy them by the pallet so you may end up with more than you need. (Shades of Gerard Hoffnung)

Answer 7

Ask a Mason, thy're good at things like that.

Answer 8

divide length of blocks into the height times the width of garage.
