<p>The first is called a cube and is a $3D$ figure where each dimension is equal in length. Basically a $3D$ square. A rectangular box, or rectangular prism, is like the $3D$ version of a rectangle. Finally, a cylinder can be thought of as a stack of circles. Just circles stacked endlessly on top of each other to a certain height.</p>
<p><strong><span style="color:#e74c3c;">WARNING</span></strong>: We have heard some reports from recent test takers that other $3D$ shapes have been tested, including cones, pyramids, and spheres. No GregMat team member has verified these reports personally, but it does not mean that they're not true. Hopefully, if a strange $3D$ figure does end up on your test, formulas for volume and surface area will be provided.</p>
