Steve’s Chestful Challenge
A real Bedrock Edition target
Steve is going for the Bedrock Edition Chestful of Cobblestone achievement. It asks a player to mine cobblestone and put a chestful of it in a chest.
Steve wants to know how many blocks fill one single chest. It has 27 slots, and every full cobblestone stack contains 64 blocks.
Fill the chest
Each square below is one chest slot. Every slot holds one full stack of 64.
Steve notices a cube hiding in the chest
One stack of 64 cobblestone can form a solid 4 × 4 × 4 cube. The chest holds 27 of those stack-cubes.
Steve arranges the 27 stack-cubes in a 3 × 3 × 3 array. He claims they make one solid 12 × 12 × 12 cube with no blocks left over.
4 × 4 × 4 = 64
3 along each direction
One chest. Two volume models. Then Steve builds with the result.
Prove it, then build

Is Steve's solid-cube claim correct? Find the cube's volume, then compare it with your chest total from page 1.

After filling the chest, Steve uses its cobblestone to build a closed, one-block-thick hollow vault. The outside is 12 × 12 × 12, and the empty inside is 10 × 10 × 10.
How many cobblestone blocks does the vault use? How many are left?
