Final answer:
Squared stones laid in a pattern without precise cuts are known as cobblestones, differing from mosaics which are detailed designs made with small colored pieces.
Step-by-step explanation:
Squared stones that have been laid in a pattern without being cut to specific dimensions are typically referred to as cobblestones. Cobblestones are not to be confused with mosaics, as mosaics involve creating images or patterns with small pieces of colored tile, stone, or glass. The mosaics are made durable by gluing these pieces to walls, ceilings, or floors, and then sealing them with grout. In contrast, cobblestones are often used for paving roads and do not form intricate designs like mosaics.
