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)
Best Answer
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.
