The straw is placed diagonally in the rectangular prism, therefore, the length of the straw is √109 inches
<h3>How to find the diagonal of a rectangular prism?</h3>
Diagonal of a rectangular prism = √(l² + w² + h²)
Where,
- l = length
- w = width
- h = height
Therefore,
l = 6 inches
w = 3 inches
h = 8 inches
diagonal = √(6² + 3² + 8²)
diagonal = √36 + 9 + 64
diagonal = √109 inches
