Tomas needs to cut a piece of wood for a model airplane he is building. He has four pieces of wood: 5 feet, 4 feet, 6 feet, and

blagie [28]

Answer:

Step-by-step explanation:

Alright, lets get started.

Tomas has four pieces of wood having each length = 5, 4, 6 and 3

The length of wood he needs to cut to make a model airplane = $\sqrt{11}$

Simplifying, it is 3.32 feet long

Means he needs more than 3 feet but less than 4 feet of wood piece.

So, he should select 4 feet length of wood because selcting 3 feet will not fulfilled to make his model and selcting 5 and 6 feet will have more unused wood.

4 feet piece of wood he should cut to have the least amount of unused wood. : Answer

Hope it will help :)
