There exists the same question from other source that shows the two boxes.
Box 1 has a length of 4/5 feet
Box 2 has a length of 3/4 feet
Because Ebony is trying to find the total amount of
space needed to hold the boxes, use addition.
Here, is the solution:
= 4 / 5 + 3 / 4
= (16 + 15) / 20
= 31 / 20
So, Ebony can make a shelf at least 31/20 feet wide or 1 11/20 feet.
