Question

. Donny had a board that had a length of 10 feet. He used the board to make two shelves. One shelf had a length of 4 feet, and the other shelf had a length of 3 feet. What is the length of the remaining piece of board?

Answer 1

The remaining piece of the board after making two shelves, one of 4 feet and another of 3 feet from an original 10-foot board, is 3 feet long.

Step-by-step explanation:

Donny had a board that was 10 feet in length and used it to make two shelves. To find the length of the remaining piece of the board, we subtract the lengths of the two shelves from the total length of the board. The first shelf is 4 feet long and the second is 3 feet long. So, the calculation is as follows:

• Total length of board = 10 feet
• Length of first shelf = 4 feet
• Length of second shelf = 3 feet
• Remaining length = Total length - (Length of first shelf + Length of second shelf)

By plugging in the numbers:

Remaining length = 10 feet - (4 feet + 3 feet)

Remaining length = 10 feet - 7 feet

Remaining length = 3 feet

Therefore, the length of the remaining piece of the board is 3 feet.
