Question

if the thickness of 400 sheets of paper is the 4 centimeters. what would be the thickness of 75 sheets of this paper. plz tell it's answer​

Answer 1

Answer:

thickness of 1 paper = 4.2/400

=0.0105

than thickness of 700 paper

= 0.0105×700

=7.35 cm thickness of 700 paper

Answer 2

Answer:

Here, 400 sheets = 4 centimeters = 40 milimeters

Thus,

400 sheets ÷ 40 millimeters = 10 sheets/milimeter

1 millimeter = 10 sheets

0.5 millimeters = 5 sheets

70 sheets =7 millimeters

+ 5 sheets = 0.5 millimeters

75 sheets. = 7.5 millimeters

Therefore ,the answer is 7.5 millimeters
