40 m^3 (meters cubed) Mass doesnt matter

Length x Width x Height= volume

V = 5 x 2 x 4 m ³
V = 40 m ³

Assuming it is a box ("rectangular parallelopiped"),
the volume is simply 5m * 2m * 4m
= 40 m3
(forty cubic meters).

Now, if the thing is NOT a box, then volume is less and density is greater.
If the length, width, and height are those of an ellipsoid (a sort-of roundish thin, like a football), then the volume would be a lot less (maybe 3/4 or 2/3 and the density would be proportionately more.
It the ends are pointy and the object looks like two pyramid stuck together, then the volume is even less.
If it's some kind of "star" shaped thing, with a long, thin spike stretching 5 meters along from the center, and another stretching 2m upward, and a third one perpendicular to the other two and stretching a total of 4m,
THEN the volume could actually approach zero (containing 300g) and the density would approach infinity!

----

The mass has nothing to do with the volume, but its density would be 300g / 40m = 7.5 g/m3.
In MKS units, this is 0.075 Kg/m3;
in cgs units, it is 7.5 g / 1,000,000 cm3
or 7.5 E -6 g/cm3
(where E indicates ten raised to a power).

That's pretty darn light!!!!!
If filled with water, the mass of such a box would be 40 million Kilograms (or 40 Metric tonnes), since a cubic meter of water is 1000Kg (=1,000,000 grams or 1 Metric tonne).

----

Maybe it's a gas????
A box full of gas, with those dimensions an a mass of 300g? I don't think so!

At standard temperature and pressure (STP), one mole of a gas occupies about 22.4 liters. Since a cubic meter holds 1000 liters, a box of the size you describe would contain about 40,000 liters, it would hold about 1785 moles (NO, not the rodents! It's a gas.)

The mass of one mole is equal to its atomic weigh in grams. For water (or stream), that's 18g (since O is 16, and each H is 1); the mass is 2 for Helium, and 1 for Hydrogen. If your box is filled with stuff that has a mass of 300g, then it cannot be any real substance at STP.

A 300g box with those dimensions would be mostly vacuum.

volume (v) = length (l) x width (w) x height (h)

for this question:

v = 5 meters x 4 meters x 2 meters = 40 cubic meters = 40 m^3

you need the mass if you want to compute for density. since the volume is in m^3, we will convert the grams to kg.

1 kg = 1000 grams. so 300 grams/1000 grams = 0.300 kg.

density = mass/volume = 0.300 kg/40 m^3 = 0.0075 kg/m^3

To get volume, you just need to follow the very simple equation of length (times) width (times) height

5 x 2 x 4
= 40

since it's in meters and you're looking for volume the correct unit is meters cubed

so your answer is 40m^3

Assuming it is a cube, 40 (5 x 2 x 4) cubic meters. The mass won't help unless you are trying to calculate density.

5 x 2 x 4= 40
40 meters cubed (do the m to the 3rd power i cant type it)

I'm assuming it is a cube.

The volume is l*x*h, or 5*4*2 = 40

40 cubic meters.

2007-10-06 16:05:59 · answer #9 · answered by tsully87 3 · 0 0

the volume should be 5 times 2 times 4 = 40m^3.
