Minecraft wiki entry for Block_of_Gold, associated text: In Xbox 360 Edition, before TU19, four gold blocks stacked on top of an obsidian block could be found inside the tutorial world's desert pyramid. This is a reference to Achievement Hunter's Let's Play Minecraft series, in which this combination is used to create the "Tower of Pimps" (seen right), a structure first created by Gavin Free, which is now used in many episodes as a trophy.
If one block is considered to be equal to one meter³, then one block of gold has a mass of 19,320 kilograms, making it the heaviest real-world matter available in vanilla Minecraft if element blocks are not considered. A player's inventory has 36 slots, with each being able to carry 64 gold blocks; therefore, a player can carry a maximum number of 44,467.2 tons of weight, not considering armor or putting things in shulker boxes (theoretically increasing the weight by 27 times).
