10. You're talking about the formula for calculating the mass of iron plate
in physics, mass m = density of object ρ× The volume of the object is V, so it is necessary to measure the length, width and thickness (CM) of the iron plate first, and multiply the three to get the volume in cubic centimeter. And then multiply it by the density of iron, 7.86 grams per cubic centimeter
for example, the size of iron plate is 500 * 100 * 10cm
the mass m of iron plate is: 500 * 100 * 10 * 7.86 = 3930000 g = 3930 kg = 3.93 t
