Answer 2

$\large\bold{\underline{\underline{ANSWER :-}}}$

$\bf\pink{Given :}$

Five copies of a book are stacked on top of each other.

Each book has 500 pages

Thickness of each page = 0.00065 cm

$\bf\blue{To\: Find :}$

Height of the stack

$\bf\green{Solution :}$

Height of stack = No. of pages × thickness of each page × no. of books

= 500 × 65 × 10¯⁵ × 5

= 162500 × 10¯⁵

= 1625 × 10¯³

Therefore,

$\sf\boxed{Height=1625×10^{-3}}$
