 For today, we did our lab on determining aluminum foil's thickness. It was easy and fun lab, we ever had. In order to find thinkness(height) first we needed to know it's length,width,and weight, since aluminum foil is really thin it hard to measure without specalized tool, so we need to use math to find it

when we found out the length,width, and weight. we need to put them in to equation.(density is given)

Formula

 Density(cm3/g)=Gram(g)/volume(cm3)

#volume is equal to (length)(width)(height)

and let height represent x

For example, length:16.80cm width:14.85cm height:x density:2.70g/cm3 gram:1.00

2.70cm3/g=1.00g/(16.80cm)(14.85cm)x
2.70cm3/g=1.00g/249.48x
1.00g/2.70cm3/g(249.48cm2)=x(thinkness)
therefore   x=0.0015cm

In this lab we have practiced how to use density formula
