Nathan is building a tree house. He needs wooden boards that are 16.45 feet, 7.3 feet, and 12.8 feet in length. What is the closest estimate of the total length he needs, in feet, to make sure he has enough wood for the tree house? (1 point) Responses 30 30 35 35 38 38 40

Answer 1

To estimate the total length of wood Nathan needs, we can round each measurement to a more manageable number and then add them together:

• 16.45 feet can be rounded to 16 feet.
• 7.3 feet can be rounded to 7 feet.
• 12.8 feet can be rounded to 13 feet.

Now, we add these rounded numbers:

\[ 16 + 7 + 13 = 36 \text{ feet} \]

The closest estimate from the options provided (30, 35, 38, 40) is 35 feet.
