Solution: Suppose x blocks are required.
8×8)x=6×6×80
64x=2880
x=45A: 45 blocks are required.
Originally, the area of each square brick was 6 6 = 36 square decimeters, and 80 pieces totaled 36 8 = 2880 square decimeters, which is the area of the entire living room. >>>More
6 6 80 = 2880 square decimeters.
2880 8 8 = 45 blocks. >>>More
