1. A carpenter needs 4 boards, each 2 feet 10 inches long,. If wood is sold only by the feet, what is the minimum length, in feet, of wood he must buy?
- A. 9
- B. 9
- C. 9
- D. 9
Answer: Option D
Explanation:
One board is 2 feet 10 inches long.
Fours boards= 8 feet 40 inches long.
40 inches= 3.33 feet. So four boards= 11.33 feet.
Because wood is sold only by feet, the minimum length of wood he needs to buy is 12 feet.
