Surface area formula
Here, we provide you with a comprehensive list of surface area formula for some common threedimensional figure.
Cube:
Surface area = 6 × a
^{2}
Right circular cylinder:
Surface area = 2 × pi × r
^{2} + 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 × r
^{2}
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r
^{2} + pi × r ×( √(h
^{2} + r
^{2}))
pi = 3.14
r is the radius
h is the height
l is the slant height
Right square pyramid:
Surface area = s
^{2} + 2 × s ×
l
s is the length of the base
h is the height
l is the slant height
