How much does 1 inch thick 96 x 120 inches steel weigh?

in carbon steel it will weigh 3,267.2 lbs.

For weight of we have to know:-

1. volume (in cubic centimeter)

2. density

so now

1 inch = 2.54 cm

96 inch = 96*2.54=243.84

120 inch = 120*2.54=304.8

so

volume=(2.54*243.84*304.8)=188779 cubic cm

density = 7.8g/cm3 (varies based on alloying element from 7.8 to 8.05)

now mass= density*volume

m= 7.8*176980.29=1472476.022 gram= 1472.5 kg=3246.25 lbs (depends on density)
