To find the number of bricks required to build the room, we need to calculate the volume of the room and then divide it by the volume of a single brick to determine how many bricks are needed.Room dimensions: Length = 8 m Height = 6 m Thickness = 22.5 cm = 0.225 mBrick dimensions: Length = 25 cm = 0.25 m Width = 11.25 cm = 0.1125 m Height = 6 cm = 0.06 mNow, calculate the volume of the room: Volume of room = Length × Width × Height Volume of room = 8 m × 0.225 m × 6 m = 10.8 cubic metersNext, calculate the volume of a single brick: Volume of brick = Length × Width × Height Volume of brick = 0.25 m × 0.1125 m × 0.06 m = 0.0016875 cubic metersNow, divide the volume of the room by the volume of a single brick to find the number of bricks required: Number of bricks = (Volume of room) / (Volume of brick) Number of bricks = 10.8 cubic meters / 0.0016875 cubic meters/brickNumber of bricks ≈ 6400So, 6400 bricks are required to build the room.
