To determine how much mortar you need for your project, calculate the area to be covered and the thickness of the mortar layer. Multiply the area by the thickness to find the volume of mortar needed.
If most of the off-cuts are also used then you will need 315 slabs. Otherwise you will need a lot more.
Depends on the linear dimensions of both the slabs and the ground.
To lay 67 2x2 slabs, you typically need a mix of sand and cement for the mortar or concrete. For a standard slab, you might use a 1:3 ratio of cement to sand. Assuming each slab requires around 0.1 cubic meters of concrete, you would need approximately 6.7 cubic meters of concrete total. This translates to about 1.67 cubic meters of cement and 5 cubic meters of sand, though actual requirements can vary based on specific project details and mix ratios.
The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions. 21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs. To complete the rectangular area, 14.2 x 12.9 = 183 slabs.

You will need 63 44cm x 44cm slabs to cover that area.
Generally speaking, masonry joints are typically ground out to at least a depth of 3/4". If your mortar is unuaually soft or loose you may need to go deeper.
Joe needs 460 paving slabs to surrond the pond.
To determine how many slabs are needed for one square meter, first convert the dimensions of the slabs from millimeters to meters. A 600mm x 600mm slab is 0.6m x 0.6m, which has an area of 0.36 square meters. Therefore, to cover one square meter, you would need approximately 2.78 slabs. Since you can't have a fraction of a slab, you would need 3 slabs to cover one square meter.
Mix water with the mortar mix until it is a paste-like consistency. Then dip some of the mortar mix out with a hand trowel and turn the trowel upside down. If the mortar clings to the trowel blade, the mixture is perfect.
For every block, you will use approximately 1.2 pounds of mortar
