Answer 2

Given,

In a stack there are $8$ books each of thickness $28mm$ and $10$ paper sheets each of thickness $0.015mm$.

The thickness of $8$ books $= 8\times 28$

The thickness of $8$ books $=224mm$

The thickness of $10$ paper sheets $= 10\times 0.015$

Thickness of $10$ paper sheets $= 0.15mm$

The total thickness of stack $=$ thickness of $8$ books $+$ thickness of $10$ paper sheets

$= 224+0.15$

$=224.15mm$

Therefore, the total thickness of the stack is $224.15mm$.
