Conversation

Have you ever heard of a parallelepiped?

I think so, but I’m not exactly sure what it is.

It's a solid shape with six faces, all being parallelograms.

Oh, that sounds interesting! I’d love to learn more about it.

Root Explanation

Parallelepiped → It is formed from "parallel" (from Greek "parallelos", meaning beside one another) and "epipedon" (from Greek "epipedon", meaning a flat surface). The word describes a three-dimensional figure with opposite faces that are parallel and flat surfaces.

Memory Tip

Think of lines that are 'beside one another' ('parallel') and a 'flat surface' ('epipedon') to remember that a parallelepiped is a solid shape with parallel faces.
