1.) A sheet of paper has a length of 29 cm, a width of 8 inches, and a thickness of 0.10 mm. What is the volume of the sheet of paper in cm^3?
2.) Calculate the density in kg/m^3 of an object that measures 5 cm on each side and has a mass of 320 grams.

yrelhan4 · Answer

1 inch=2.5 cms.. 
1mm=0.1 cm.
first convert width and thickness into cms..
Volume= length*width*thickness..

then?

You can solve the first part now, right?

anonymous · Answer

Ah! Thanks :)

anonymous · Answer

How about in number 2?

yrelhan4 · Answer

Yeah you know density=mass/volume..
mass=320/1000=.32kgs
volume=5^3 (i am assuming the object is a cube here.. cant be anything else)..

Again?

anonymous · Answer

density=(mass/volume).
320grams=0.32kg
5cm=0.05m
so volume=(0.05)^3
so density=0.32/(0.05)^3=2560 kg/m^3
