====== Mortar ======

Mortar is made with clay and heap of sand. The recipe for mortar calls for equal parts (1kg) of clay and heap of sand to make one mortar.

However, one clay is 2kg and one heap of sand is 20kg.  Knowing this we can calculate the total clay and heap of sand needed to make the amount of mortar we want.

The mortar recipe calls for:

* 1kg of clay which is half of a full clay, or .5
* 1kg of heap of sand which is one twentieth of a full heap of sand, or .05

Using these values we can calculate the number of full clay and full heap of sand required.

===== Formulas =====

Prerequisites:

* Mortar is the amount of mortar we need.
* Number is the calculated number of ingredients we need.
* Kg is calculated the amount needed in kg for the ingredients.
* 1 is 1kg per ingredient.
* .5 is a half a clay, which is 1kg or the recipe amount needed per mortar.
* .05 is a twentieth of a heap of sand, which is 1kg or the recipe amount needed per mortar.


Clay:

$Number=Mortar*.5$\\ 
$Kg=Number * 1$

Heap of sand:

$Number=Mortar*.05$\\ 
$Kg=Number * 1$

===== Example =====

We need 2000 mortar

Clay:

* Number:  2000 * .5 = **1000 clay (2kg per)** needed
* Kg:  2000 * 1kg = **2000kg of clay** needed

Heap of sand:

* Number:  2000 * .05 = **100 heap of sand (20kg per)** needed
* Kg:  2000 * 1kg = **2000kg of heap of sand** needed

===== Notes =====

Keep in mind that kg and volume are two different things.  Volume is said to be represented as liters for liquid, but volume for solid objects is not explained.

A bulk storage bin has a volume column.  What you see in the volume column is not equivalent to kg.  A heap of sand is 20kg but takes up 18.75 volume in a bulk storage bin.  This is why if you have 100 heap of sand the kg is indeed 2000kg but the total volume is 1875.
