# 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 Π r^{}

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

### Surface Area of a Cone

### SA = ΠrL

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

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

### SA = (ΠrL) + Π r^{2}

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