Question

Talia is building a 12 square, wooden box and wants to put in a diagonal piece of wood. How long would the piece need to be to the nearest ?(1 point)

Answer 1

If the box is a cube with side 12, the interior diagonal is sqrt(12^2+12^2+12^2) = 12√3 ≈ 20.785.

So the diagonal piece should be about 20.8 units (≈ 21 units to the nearest whole unit, e.g. inch).
