Mining with stone pickaxe

Single stone pickaxe has 132 durability. With two pickaxes however, you can "repair"(combine) them and have 5% bonus durability which is floor(132*1.05) = 138. So my question is, what is the maximum number of stone blocks can you mine with inventory full of (36) stone pickaxes?

(Assume you can only mine stone blocks)

4962 blocks- enough to mine a solid 17x17x17 cube.

The most efficient repair possible involves two tools with a total durability of 126. This gives the maximum possible bonus of 6 extra uses.

With 36 pickaxes you will make 35 repairs.

35*6=210 bonus from repairs

The 36 pickaxes themselves will mine 132 blocks each.

36*132= 4752 blocks

4752+210= 4962 blocks mined in total.

You would want to only use 131 of those 132.uses to maximise the amount except on the last one so 131×35+210+132= 4927
