...even though i already no it i just want 2 c if u can figure it out................a cube has 2cm lenghth,4cm wide.0.5 cm height,and it weights 10 grams calculate the density!!!!!!!!

how can it be a cube if its sides are different legnths?

First off, a cube cannot be 2 cm long, 4 cm wide, 0.5 cm high because those dimensions do not define a cube. A cube is a three dimensional object that has equal length, width, and height.
However, to find the density any object, calculate the volume of the object and then use the basic definition of density.
Density = mass/volume

hows it a cube?? the side lengths are the same in a cube.
anyways...the volume is 2cm x 4cm x 0.5cm = 4cm^3
1 cm^3 = 1ml
Therefore, the volume of the "cube" is 4 ml
density equals mass divided by volume
= 10g / 4ml
= 2.5 g/ml
therefore the density of the "cube" is 2.5 g/ml

LOL, density is mass/volume...
Given that the mass is 10 grams and the volume is 4 cm^3
Then the density is 5/2 grams per cubic centimeter.

You don't want the answer. You just want to test others. Sorry , sir. I don't have time to undergo an examination. But a small doubt, where did you learn that a solid with different dimensions is a cube?

I do qualify as a nerd, but I'm a square and not a cube (actually I'm a round) so your question beats the heck out of me. With the correct proportions one of my grand kids could figure it out. However, it does not appear cube shaped to me, either.

Your cube is a very strange one. However assuming you mean its size is as you say, then...
2cm x 4cm x 0.5cm = 4cm³ (cc).
Mass = 10g.
Density = Mass/Volume = 10g ÷ 4cc = 2.5g/cc
