Each board has area of (4 x 8) = 32 square feet.
Number of boards = (400 / 32) = 12.5 boards
It depends on the size of the boards.
First, calculate the area of one board: a 6-inch by 8-foot board has an area of 6 inches (0.5 feet) by 8 feet, which equals 4 square feet. To cover 300 square feet, divide 300 by 4, resulting in 75 boards needed. Therefore, you will need 75 boards to cover 300 square feet.
7*4 =28 square foot boards 192/28 = 6.857142857142857 = 7 boards

To cover 658 square feet using 16 feet x 6 inch boards, we first need to convert the board dimensions to the same unit. Since 6 inches is half a foot, the boards are actually 16 feet x 0.5 feet in size. This gives a total area of 8 square feet per board. Therefore, 658 square feet would require 658 / 8 = 82.25 boards, but since we can't have a fraction of a board, you would need 83 boards to cover 658 square feet.

6 inch = 1/2 foot so each board is 16 x 1/2 = 8 square feet 200/8 = 25 boards
