Answer: Kayla used 2 5/24 cups of paint all together.
Step-by-step explanation:
Kayla paints a bookcase by using
 1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.
She also used 3/8 cup of paint on the inside.

2 5/24 cups of paint
