Answer:
25 wooden boards
Step-by-step explanation:
Given that:
Width of wooden board = 6 inches
Number of boards required to build a fence of 150 inches long if there are no gaps :
The lenght of fence / width of wooden board
= 150 inches / 6 inches
= 25 wooden boards
The mixed number will be 13 3/4.
B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units
The prefix "milli-" means "one thousand"
