Answer 1

To estimate the total length of wood Nathan needs, we can round each measurement to the nearest whole number:

• 16.45 feet rounds to 16 feet.
• 7.3 feet rounds to 7 feet.
• 12.8 feet rounds to 13 feet.

Now, we can add these rounded numbers together:

16 + 7 + 13 = 36 feet.

Therefore, the closest estimate of the total length Nathan needs is 35 feet.
