3D Objects (Prisms, Cylinders, Cones, Spheres)
Three‐dimensional objects are the solid shapes you see every day, like boxes, balls, coffee cups, and cans.
Here are some helpful vocabulary terms for solids:
 Face: a flat side of a 3‐dimensional object.
 Base: one of two parallel, congruent sides of an object.
 Edge: the intersection of two faces on a solid object. This is a line.
 Prism: a solid object with two congruent and parallel faces.
 Pyramid: a solid object with a polygon for a base and triangles for sides.
