A rectangular iron plate weighs 425kg, 5 meters long, 2 meters wide and 6 cm thick. How many grams does each cubic centimeter iron plate weigh?

A rectangular iron plate weighs 425kg, 5 meters long, 2 meters wide and 6 cm thick. How many grams does each cubic centimeter iron plate weigh?


425000 ÷ (500 × 200 × 6) = 425 / 240 and 37 / 48 (g) ≈ 1.77 (g)



A rectangular iron plate weighs 480KG. It is 2m long, 1.5m wide and 2cm thick. How many kg does it weigh per cubic decimeter? (solved by equation)


20*15*0.2*X=480
x=480/60
X=8
