Answer:

156

Step-by-step explanation:

We are given that

Length of cardboard, l=69.9 cm

Width of cardboard, b=24 cm

Height of cardboard, h=36.01 cm

Length of book, l=22 cm

Width of book, b=19.5 cm

Thickness of book, h=0.9 cm

Volume of cuboid=lbh

Using the formula

Volume of cardboard=[tex]69.9\times 24\times 36.01 cm^3[/tex]

Volume of one book=[tex]22\times 19.5\times 0.9 cm^3[/tex]

Number pf exercise book=[tex]\frac{volume\;of\;cardboard}{volume\;of;one\;book}[/tex]

Number of exercise book=[tex]\frac{69.9\times 24\times 36.01}{22\times 19.5\times 0.9}[/tex]

Number of exercise book=156
