Measuring Guide - Aggregates.

Measuring the area you want to add aggregate to can be quite daunting, we have added some information here that may help you.
It is very important that you order approximately 5% - 10% extra aggregate for filling odd spaces and to cover the inaccuracy of measurements.
To measure the area, its a good idea to make a sketch to assist you with your calculations, multply the average length by the average width and depth to determine the amount of aggregates you will need.


 
Rectangle & Square

What units are you measuring in:
Calculate Rectangular area
Finding the area in a rectangle is simple.
Multiply the short side by the long side then multiply the depth.
No fancy tricks, just length times width times depth.
Its the same with the square area, multiply the two sides then the depth.

Rectangle = Length x Width x Depth
Square = Length x Width x Depth
The factor used in the calculations is 2 and all values are rounded up to the nearest full bag
Length = Width = Depth =     
Total =    Bulk Bags Required
 
Circles

What units are you measuring in:
Calculate Circular area
For a circle take the radius (that's half the distance across the middle of the circle) and square it.
If the circle is 20 feet across take half of that (10) and multiply it by its self then multiply it by the depth, ensuring that you do it in the same units.

Circle's Volume = (3.14 x Radius˛) x depth
The factor used in the calculations is 2 and all values are rounded up to the nearest full bag.

Radius = Depth =      Total =    Bulk Bags Required
 
Triangles

What units are you measuring in:
Calculate Triangle area
Right-Angled Triangles are kind of like rectangles, taking calculations form a right angle multiply a x b then divide by 2 then multiply by the depth.
This only works with RIGHT-ANGLED triangles.
That means that one corner has to be square (90°).
Triangle's Volume = ((a x b) ÷ 2) x depth
The factor used in the calculations is 2 and all values are rounded up to the nearest full bag

A = B = Depth =      Total =    Bulk Bags Required


Calculate Triangle area

If your triangle isn't right-angled you need to find the area of an irregular triangle and cut it into two pieces.
Start at the corner opposite the longest side.
Go straight towards the long side, making two right-angled triangles.
Now find the area for each one of the little triangles.
Add them together to get the total area of the triangle.
 
Irregular Shapes

If your area is of an unusual shape, draw a sketch of it and then by using the four shapes above you can break it up into smaller shapes and calculate from there!
