all you need to know is that 1000 cm^3 (cubic centimeter) = 1 Liter and that the density of water is 1 gram/cm^3

#1. 1 m^3 = 1,000,000 cm^3 (100^3)

1,000,000 cm^3 = 1000 L (1,000,000 / 1,000)

#2. the volume of the box is 48,125 cm^3, so the mass of this much water in grams is 48,125 grams (b/c the density is 1 gram / cm^3) and is 48.125 kg

#3. 455 cm^3 of water is 455 grams, so it is .455 kg

all your solutions so some distance for sure do not actual comprehend what the dimension difficulty is. The dimension difficulty is a edge of quantum mechanics. In quantum mechanics the state of a equipment is defined by making use of a function this is actual a superposition of feasible states. An operator acts in this function to offer the fee for a actual quantity – yet using fact the state is a superposition of feasible values then the operator can in simple terms supply the risk of a series of values. working example, electrons have spin. Spin could be in any course. In a 2 electron equipment, the spin of one electron would be in any course, and the different interior the different course. Now in case you ask the query “what’s the spin of electron A”, QM can in simple terms supply you with a risk for an answer. yet once you diploma the spin you will get a distinctive fee, and given which you will comprehend the state of electron A and for this reason you will additionally comprehend the state of electron B (this is the different). the difficulty quite is that in the time of the previous the dimension the equipment replace into defined by making use of a superposition of states, yet after it it rather is in a time-honored state. How did this alteration? it rather is rarely an fact query, although. The time era dimension is incredibly unfastened right here, and actual has no sparkling meaning. quite its approximately announcing while a macroscopic classical equipment (like a guy or woman) interacts with a microscopic quantum equipment then something occurs to the state function of the microscopic equipment. The macroscopic equipment would not could be an observer, or smart or maybe sentient. It in simple terms has to engage. So the time era dimension difficulty is an extremely undesirable call for it. there isn’t any rather passable interpretation of this predicament in physics. the main elementary reported is the so called Copenhagen Interpretation – this is rather a cop out interpretation that could effectively be shown to fail or have flaws in lots of circumstances.
