Answer:The height of one book is

in
Explanation:We know that the 3 books are of the same size. This means that the 3 books have the same height.
Assume that each book has a height x in
Now, we know that the total height is 10 in.
Therefore:
x + x + x = 10
3x = 10
x = 10/3 in
Based on the above, the height of one book is 10/3 in
