Formulas for Common 3D Shapes
Sphere (Ball) Surface Area
A sphere is a perfectly round geometrical object in three-dimensional space.
A = 4 π r2
Cone Surface Area
A cone is a three-dimensional shape that tapers smoothly from a flat base to a point called the apex.
A = πr(r + √(h2 + r2))
Where r is the radius of the base and h is the height.
Cube Surface Area
A cube is a regular polyhedron with 6 congruent square faces.
A = 6 a2
Where a is the length of an edge.
Cylindrical Tank Surface Area
A cylinder has two parallel circular bases at a distance h from each other.
A = 2πr(r + h)
