Calculate the area of the hall. 8x4 = 32 square meters. Then calculate the area of the brick. 0.3x0.3 = 0.09 square meters. Then divide the total area into the area of the brick to get how many pieces you need. Divide 32 into 0.09 = 355.555 pieces, and multiply by 6 yuan / piece. 355.5x6 = 2133 yuan
