Answer:
6 : 5
Explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = l = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
l = 4(3) = 3(4) = 12
w = 3+3+4 = 10
Then the ratio l : w is 12 : 10 = 6 : 5.
