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
