Final answer:
To cover a wall that is 24' wide x 6' high with 1x6x8' boards, we need 18 boards.
Step-by-step explanation:
To cover a wall that is 24' wide x 6' high with 1x6x8' boards, we need to calculate the number of boards needed. First, we need to determine the width of the wall in terms of the length of the boards. Each board is 8' long, so we divide the width of the wall (24') by the length of each board (8') to get 3 boards. Next, we need to determine the height of the wall in terms of the width of the boards. Each board is 6' tall, so we divide the height of the wall (6') by the width of each board (1') to get 6 boards. Finally, we multiply the two results to get the total number of boards needed: 3 boards x 6 boards = 18 boards. Therefore, the correct answer is not provided in the options given.
