democritus calculated the volume of pyramids and cones

Cones have curved lateral surface, pyramids don't.

There is no universal formula for volume: it depends on the shape. There are formulae for the volumes of some shapes such as cuboids (including cubes), cones, ellipsoids (including spheres), regular polyhedra (including pyramids), prisms (including cylinders). But there are many more irregular shapes for which no formulae exist.

The biggest impact I think of: Calculus is how people invented the formulas to get the volume and surface area of spheres/cones/pyramids.

yes by: Mia Summers :):D

It means that the shape of the object doesn't fit into a small list of predefined shapes (for which simple formulae for volume and surface area are known). Such a list may typically include shapes like spheres, rectangular boxes, cylinders, pyramids, cones, certain sections (cutouts) of the previous ones, etc.

Pyramids, no; cones, yes (except the base).

There are different formulae for spheres, ellipsoids, cones and pyramids, paralellepipeds as well as some other shapes. For other shapes, including irregular shapes, the fluid displacement method may be the only option.

cones have round bases

Cones do but pyramids don't
