thick.

of 15,000 sheets?
(ii) How many sheets will be there in a
stack 15 cm thick?​

Answer 1

ANSWER

thickness of 1071 sheets = 6.3 cm

thickness of 1 sheet = 6.3/1071

= 0.0059 cm

thickness of 1500 sheets will be= 0.0059×1500cm

= 8.9 cm is the answer

². sheets in 6.3 cm stack = 1071

sheets in 1 cm stack= 1071/6.3

=170 sheets

so sheets in 15 cm thick stack = 170 × 15 sheets

= 2550 sheets is the answer
