SURFACE AREA IN GEOMETRY

Surface Area of a Cube

SA = 6x^2

where: SA is the surface area and x is the side of the cube

Surface Area of a Cuboid

SA = 2(xy+yz+zx)

where: x, y and z are the adjacent three sides of the cuboid

Surface Area of a Sphere

SA = 4 pi r^2

where: r is the radius of the sphere and pi = 3.14

Surface Area of a Cone

SA = pi x r x L

where: r is the radius of the cone and L is the slant height of the cone and pi =3.14

Total Surface Area of a Cone (including the area of the base)

SA = (pi x r x L) + pi x r^2

where: r is the radius of the cone and L is the slant height of the cone and pi =3.14
