A structural I steal beam has a density of 7.56 x 10^3 kg/m^3.
What is the mass of a section 1.50 m long?
And it shows a figure of an I beam, the top is 15 cm long, the side is 36 cm long, the widths of the 3 parts of the I are 1.cm wide.
so m=pV, I know the density, but how do I figure out the volume?
Somethin to do with Area times height, but I'm not gettin it right....
I got .54m^3 as the volume and that's wrong.....
