Question

what is the density of a sheet of aluminum that has a volume of 328.4 cubic centimeters and a mass of 780 grams

Answer 1

`\large\boxed{density=(1950)/(821)\ (g)/(cm^3)\approx2.375\ (g)/(cm^3)}`

Explanation:

`density=(mass)/(volume)\\\\\text{We have}\\\\mass=780\ g\\volume=328.4\ cm^3\\\\\text{Substitute:}\\\\density=(780g)/(328.4\ cm^3)=(780\cdot10)/(328.4\cdot10)\ (g)/(cm^3)=(7800)/(3284)\ (g)/(cm^3)=(7800:4)/(3284:4)\ (g)/(cm^3)\\\\=(1950)/(821)\ (g)/(cm^3)`
