What is the massof a 15cm cube of lorn if the density of iron is 78grams/cm

Mass, m = 1170 grams

Explanation:

Side of a cube of iron is 15 cm

Density of iron is

It is required to find the mass of the cube of iron. Density is given in terms of mass and its volume as :

m is mass of iron cube

So, the mass of the cube of iron is 1170 grams.

true is the correct answer

hope i

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
