The length of the tape measures 20 inches, which is 1 inch more than the shortest distance around the box. Find the dimensions of the box.
--------------------------------------------------------
l = w
Nothing is said about the height; I'm going to assume its height is "w".
-----------
A wrap-around is w+w+w+w long
--------------------
Inequality:
tape = 4w+1 inches
20 = 4w+1
19 = 4w
w = (19/4) inches
