Answer:

yes

Step-by-step explanation:

You can go at this a couple of ways:

1. The total length David needs is (1.75 m) × 4 = 7.00 m. His 7.28 m piece is long enough to provide the pieces he needs.

2. The length of each piece when the wood is cut into quarters is ...

(7.28 m)/4 = 1.82 m

This is longer than the 1.75 m needed, so each piece is long enough.
