Shape of the Earth.
The Earth's shape is very close to an oblate spheroid, although the precise shape (the geoid) varies from this by up to 100 meters (327 ft). The average diameter of the reference spheroid is approximately 12,742 km (more roughly, 40,000 km/Ï). The rotation of the Earth causes the equator to bulge out slightly so that the equatorial diameter is 43 km larger than the pole to pole diameter. The largest local deviations in the rocky surface of the Earth are Mount Everest (8,850 m above local sea level) and the Mariana Trench (10,924 m below local sea level). Hence compared to a perfect ellipsoid, the Earth has a tolerance of about one part in about 584, or 0.17%. For comparison, this is less than the 0.22% tolerance allowed in billiard balls. Because of the bulge, the feature farthest from the center of the Earth is actually Mount Chimborazo in Ecuador (which is on the Equator).

It is almost a sphere.
It was first theorized by the Greeks because when one saw a ship coming over the horizon, that certain person would see the front first and then later the back.
Also a sphere would be one of the few mathematically correct figures.
By the way, satellites have a spherical orbit, hence the Earth must be a or like a sphere

Round with a very Slight Bulge or ellipsis at the equator do to centrifugal force

A squished sphere or "oblate spheroid". It sticks out the tiniest bit around the equator. That's because of the spin.

It's pretty close to being a perfect sphere. It is a little larger around the equator that if you were to go from north pole to south pole and back.

the shape of the earth is spherical round like the shape of an oval egg.

Oblong spheroid.
The Earth is not a cube because it bulges at the equator. Moreover, it is sort of like a 3D...oval shape :)
