How do you find the volume of a solid cubic figure?

You would multiply Length*width*height

Cubic means it is 3D and also that it is a cube

a cube is like a square because all the angles are the same and the sides are all the same legnth so

volume=length times width times height

for cube, legnth=width=height so

volume=height cubed or to the thierd power or ^3
