    First of all, the length of each bell is divisible, and there is no remainder.

    5m*8m=40m²

    The area of 2dm is 1000 pieces, and the area of 3000 yuan is 5dm, and 160 pieces are needed, and 2720 yuan.

    The number of square bricks with a side length of 2dm is required: 80 50 (2 2) = 1000 3 1000 = 3000 yuan.

    The number of square bricks with a side length of 5dm is required: 80 50 (5 5) = 160 17 160 = 2720 yuan.

    It is cheaper to choose a square brick with a side length of 5dm, which is 3000 2720 = 280 yuan.
