NoteIn this article we are covering important 3D Shapes formulas.

A 3D shape is a shape that is bounded by a number of surfaces or planes. These are also referred to as solid shapes. These shapes have height or depth unlike 2D shapes; they have three dimensions- length, breadth and height/depth and are therefore called 3D figures. For 3D shapes we measure Volume (V), Curved Surface Area (CSA), Lateral Surface Area (LSA) and Total Surface Area (TSA).

All 3D Shapes can be described in the terms of their faces, vertices and edges.

  • Face – a flat or curved surface
  • Edge – line where 2 faces meet
  • Vertex – point where 3 or more edges meet

s = side

Volume: V = s3

Surface Area: TSA = 6s2
