3D Shapes: Nets, Surface Area & Volume
by Anonymous
Fold and unfold nets to see how surface area sums the faces and volume comes from base area times height in prisms and cylinders.
About this app
An interactive middle-school math app for exploring cuboids and cylinders through their nets and 3D views. Adjust dimensions, switch between unfolded and solid shapes, and see surface area and volume calculated with visual explanations. A challenge section provides multiple-choice questions and tracks consecutive correct answers.
