Cuboids and triangular prisms in 3D

Mathematics3D GeometryAges 12–13

A cuboid (a × b × h) or a right prism whose base is a right triangle (legs a, b and height h) is drawn in space; drag to rotate it and see its faces, edges, and vertices. The lateral surface area, total surface area, and volume are calculated with formulas that update as you change the dimensions; turn on the net view to see the side faces unfold into a rectangle whose length equals the base perimeter.
