Does the earth have a transform for calculating its volume and becomes a cube.?

    The volume of a sphere is 4/3 pi() r^3

    and the volume of a cube is L^3

    so to transform a sphere into a cube of the same volume you have

    4/3 pi() r^3 = L^3

    (4/3 pi()) ^ (1/3) * r = L

    or r = L/ ( 4/3 pi() )^(1/3)

    (4/3 pi() )^(1/3) ~= 1.396

    So as a cube 1.306 r = L

    or r = L / 1.396

    So there are some things you may notice. The cube has a lower distance across than a sphere of the same volume which means that you can pack more cubic boxes in a space than spheres.

    If you calculate the surface area / volume for each the sphere has the lowest surface area/ volume. This makes a sphere the most efficient shape for resisting pressures.

    Including gravitational pressure. So mountains wear down to gradually approach a smooth spherical shape.

      The only part that is wrong is the calculation of (4/3 pi())^(1/3) I don't know what I pressed but I did it again to get 1.611992 However I did give the full statement immediately above it. ie (4/3 *pi())^ (1/3) is the correct figure.

    Vs = 4*PI/(3*8)*d^3 = PI/6*d^3 = 0.52360*d^3

    Lc = d*³√0.52360 = d*0,80600

    The volume of the earth is around 260 billion cubic miles. So if it were a cube, each edge would be around 6400 miles. But it would adjust itself to a spherical shape as the corners would quickly "fall down" to be closer to the center of mass.

    There is no earth. It's fake.

    The earth is not intelligent and not capable of calculating anything.

      The flatness of the earth is measured by its curvature or its area to volume ratio.which has the same form in a cube
