Surface area formula

Here, we provide you with a comprehensive list of surface area formula for some common three-dimensional figure.

Cube:

Surface area = 6 × a²

Right circular cylinder:

Surface area = 2 × pi × r² + 2 × pi × r × h

pi = 3.14
h is the height
r is the radius

Rectangular prism:

Surface area = 2 × l × w + 2 × l × h + 2 × w × h

l is the length
w is the width
h is the height

Sphere:

Surface area = 4 × pi × r²

pi = 3.14
r is the radius

Right circular cone:

Surface area = pi × r² + pi × r ×( √(h² + r²))

pi = 3.14
r is the radius
h is the height
l is the slant height

Right square pyramid:

Surface area = s² + 2 × s × l

s is the length of the base
h is the height
l is the slant height
