Show answer & explanation
Correct answer: C
To find the number of bricks, first calculate the volume of the wall and the volume of a single brick.
Convert all dimensions to centimeters: Wall = 1000 cm x 600 cm x 22.5 cm.
Wall Volume = 13,500,000 cm³.
Brick dimensions are 25 cm x 12 cm x 9 cm.
Brick Volume = 2,700 cm³.
Divide the wall volume by the brick volume: 13,500,000 / 2,700 = 5,000 bricks.
