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
