Answer:

m = 1.53 kg

Explanation:

Given that,

The sides of a book are 30cm by 25cm.

Pressure exerted, P = 200 Pa

We need to find the mass of the block. We know that,

Pressure = Force/area

So,

[tex]P=\dfrac{mg}{A}\\\\m=\dfrac{PA}{g}[/tex]

Put all the values,

[tex]m=\dfrac{200\times 0.3\times 0.25}{9.8}\\\\m=1.53\ kg[/tex]

So, the mass of the block is 1.53 kg.
