Question

A straw is placed inside a rectangular box that is 2" x 6" x 8". If the straw fits exactly into the box diagonally from the bottom left corner into the top right back corner how long is the straw?

Answer 1

Answer:
`10.2`

Explanation:

Given

The dimension of the rectangular box is
`2`

If the Straw fits exactly into the box diagonally

So, the length of the longest diagonal of the rectangular box is equal to the length of the straw i.e.

`\Rightarrow l=√(2^2+6^2+8^2)\\\\\Rightarrow l=√(4+36+64)\\\\\Rightarrow l=√(104)\\\Rightarrow l=10.19\approx 10.2`
