Beside above, how much crushed concrete do I need calculator? In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This will tell you how many cubic yards of crushed stone you need.

Concrete blocks are much easier to calculate. Each block is 450 x 215 x 100. Ten blocks will construct approximately 1 square meter of wall, with 1 bag of sand/cement mix enough for 10 blocks.

Since bags are only sold in whole (not half, or quarter) quantities, you'll need to purchase three (3) 60-lb.

bags for one cubic foot..

Multiply the square footage by the depth in feet to find the volume of the space in cubic feet. Volume is found by measuring length × width × depth. Finally, divide the cubic footage by 27 to find the volume in cubic yards. This is the amount of concrete needed.

Once you know how big the room is and ideally know how many square meters are in it, you can simply divide that figure by 9 to give you about how many bags of multi finish plaster you will need. Multi finish covers 10m2, but I say 9m2 to all allow for wastage.
