Step-by-step explanation:
the mass of one sheet of paper?
The units for density is incorrect but I will use g/cm^3 as my density so the density of a single sheet of paper is 1.20g/cm^3.
Using the equation
density=mass/volume and solving for mass gives
mass= density*volume
Volume is equal to the length*width*height
Where
length=29.7cm
the width=21.5cm
the height =?
The height of a single sheet of the paper is found by converting the 6.5mm to cm and dividing by 100
Since 10mm=1cm then 6.5mm*1cm/10mm=0.65cm
Divide the thickness of the pile by 100 gives
0.65/100= 0.0065cm.
the volume of one sheet of paper is now =29.7*21.5*0.0065=4.15cm^3
mass=density*volume
mass of one sheet of paper= (1.2g/cm^3)*(4.15cm^3)=4.98grams
