**Calculating m²**

Calculating square meterage is simple and is only required if you're laying pavers or turf. When it comes to product you want cubic meters, but we'll get to that in the part next.

First step is to measure out your length and width of the area. If it's not a typical rectangle or square **(fig 1)**, don't dispair, it's as simple as breaking the area down into sections **(fig 2). **If it's a triangle shape then follow the calculation in **(fig 3). **If it's more of a circle area then there's a few different ways to calculate it. The easiest way is to get your radius (measurement from the centre of the circle to the outside diametre) and the calculation is πxr²=area **(fig 4)**

Now that you have the length and width your set to do you the calculation. All that you have to do is Length x Width = Area (m²).

If you've broken it down into sections, calculate out each section and add them together

**Calculating m³**

Calculating cubic meters(m³) is the same premise as calculating sqaure meters(m²) its just adding the thickness of the layer you want. Perfect for working out how much drainage gravel or sand is required for your trench, roadbase for you driveway or even decorative gravels for your garden or display area

Same as square meters you need to measure your length and width of the area your working on. Now you need to work out the depth you want for the material to work. For roadbase's we'd recommend a 125mm - 150mm layer. Trenching would be 100mm - 125mm above and below the pipe (depending on the size of the pipe). Decorative gravels is entirely up to you. If you only want a thing layer of a 20mm sized pebbles, then the layer would only be 25mm.

For the calculation all that you have to do is Length x Width x Depth = Area in cubic meters **(fig 5)**. Remember when you measure your depth it will most likely be in millimeters, so it needs to be converted to meters. 150mm = 0.15m (there's 1000mm to a meter, so divide your depth by 1000 to get your depth into meters)

2) 4m x 2m = 8m²

3) 3m x 4m = 12m²

Total = 35m²

e.g. 0.5 (½) x 4m x 3m = 6m²

πxR² = Area

3.14159(π) x 5²

3.14159(π) x (5x5) = 78.54m²

10m x 6m x 0.15m = 9m³
