There is a regular hexagonal living room with a side length of 4 cm, and a regular triangle with a s

The living room in the question should be 4 meters long.

Let me tell you my idea of solving the problem:

A regular hexagon with a side length of 4 meters can be seen as a regular triangle with a side length of 4 meters.

The area of a triangle with a side length of 4 meters is 64 times that of a triangle with a side length of 50 cm, and the number of blocks required for a triangle with a side length of 50 cm is 64*6=384

Add in the gap between every 2 bricks, then there should be less than 384 bricks, but it is better to buy 384 bricks to be on the safe side.

Four meters or four centimeters! If it's four centimeters, I'll spread it all together! If it's four meters, it's 384 pieces!

The problem of purchasing materials for ground decoration, right?

Calculate the total area of the regular hexagonal living room divided by the area of a single tile equals the number of tiles, multiply it by 110% and it is the number of tiles you should buy. Negotiate with the dealer at the time of purchase, and the rest must be returned (this is customary). OK！

The side length is four meters, with 384 pieces.
