Answer 1

Answer:

here

there are two books, each book thickness is 50mm.

thickness of one page of a book is 0.015

now

0.015*4= 0.06

so, stack one 1 book is 0.06mm

therefore,

total stack = 0.06*2

= 0.12mm

Answer 2

Answer:

1 stack

2 books, each thickness 50 mm

2 books thickness-- 50 X2

100mm

1 paper sheet thickness -- 0.015mm

4 paper thickness--- 0.015x4

0.06mm

total thickness of stack --2 books thickness +4 paper sheets thickness

100+0.06

100.06mm

total thickness of stack is 100.06mm
