What is the maximum length of umbrella that could fit in a box 8" by 15"?

The maximum length of the umbrella should be 15"

Step-by-step explanation:

We can actually visualize the umbrella and comparing it in terms of length with the box

So that for the umbrella to fit into the box it length must be equal or less than the length of the box

Given data

Length of box l=15"

Width of box w = 8"

The symbol " represents inches a unit for measuring le3

Hence the maximum length of umbrella that can fit into the box is the length of the box 15"

Anything more than 15" will not fit in.
