100 dollars per book

Step-by-step explanation:

1 divide

2 multiply

3 add

First, How many sides does it have?
Second, What do you do to find the area of a surface? (Square or rectangle)
Third, Add up all of the sides.

1: 6

2: multiply the length and width
(I am just doing the sides in a random order)

Top side: 5 x 5 = 25
Left side: 5 x 5 = 25
Right side: 6.4 x 5 = 32
Bottom side: 9 x 5 = 45
Front side: (14 x 5) divided by 2 = 35
Back side: (14 x 5) divided by 2 = 35

3: 25 + 25 + 32 + 45 + 35 + 35 = 197

197

Hope this helps :D
