I need help with this question, I am uncertain as to how they got 3.2572in^4 for "J" and value 0.73749in for "py" in the solution. If you can figure out how they got these values id greatly appreciate your input thank you.

The steel grating 0.80 meter. x o.80 meters placed on top of the concrete catch basin is composed of a 10mm square bar spaced at 100mm on centers with an angular steel frame 20mm x 20mm x 6mm along the perimeter. Find the total requirement of the steel bar in kilograms and how much it will cost if 1.0 kilogram of steel amounts to PhP 45/kg. ? NOTE: Use density of steel = 7,860 kg per cubic meter.
