Question

A1.00 m long beam of stainless steel with a square 2.00 cm x 2.00 cm cross section has a mass of 3.02 kg. What is its density in grams per cubic centimeter? Round your answer to two decimal places.

Answer 1

Answer:

density = 7.55 g/cm^3

Explanation:

we need to get the volume first to get the density , and the volume formula is:

the volume = area * thickness

where :

area = 2 cm * 2 cm = 4 cm^2

and thickness = 100 cm

by substitution:

the volume = 4 * 100 = 400 cm^3

where

density = mass / volume

we have to convert mass from kg to g = 3020 g

by substitution:

density = 3020 g / 400 cm^3

           = 7.55 g/cm^3
