## Formula

The growing time of an item on a tree can be found by using its rarity, using the following equation:

In this case,

r = rarity
t = time taken to grow in seconds

$t=r^3+30r$

$\frac{t}{r}=r^2+30$

and

$r=\sqrt[3]{\frac{t}{2} + \sqrt[]{\frac{t^2}{4} + 1000}} + \sqrt[3]{\frac{t}{2} - \sqrt[]{\frac{t^2}{4} + 1000}}$

## Example

Let's say we're growing a Roshambo Block Tree with a rarity of 71. How many seconds does it take to fully grow the tree?

$t=r^3+30r$

$t=71^3+30(71)$

$t=357,911+2,130$

$t=360,041$ Now divide to get hours, days, or weeks

$360,041 / 60 / 60/ 24 = 4.16 days$
