Hi,

ReplyDeleteUsing the math formulas , I made a script with JavaScript that calculate the volume and surface area of various 3D objects (cube, barrel, prism, sphere, etc.). I post it on the page http://www.coursesweb.net/javascript/volume-surface-area-calculator-3d-objects_s2

Hope it is useful.
