if an iron cube of volume 400cm3 is immersed in water,the upthrust will be?

Question

Henry · Answer

V*D = 400cm^3 * 0.998g/cm^3 = 399.2 Grams = 0.399 kg F = M*g = 0.399 * 9.8 = 3.91 N. = Upthrust

Joshua · Answer

An iron cube of volume 800cm is totally Immersed in water calculate the upthrust

Emma · Answer

V×D=800cm^3×0.998g/cm^3=7.984g. But F= mg. F=7.984×9.8=772.432N=upthrust
