Surface area of a
sphere is defined
as the total area
covered its outer
surface. A sphere
has surface
area equal to 4 π
r2 square units.
The surface area of a cylinder can
be defined as the total space covered
by the flat surfaces of the bases of the
cylinder and its curved surface. The
total surface area of the cylinder has
two components - a curved surface
area and two flat surface areas.

Surface area of a cone is the total area
covered by its surface. The total
surface area will cover the base area
and lateral surface area of the
cone. Cone is defined as a threedimensional solid structure that has a
circular base.
Surface area of a
Prism= 2 × (Base Area)
+ (Lateral surface
area) · A prism is a 3dimensional solid object.
· It has identical ends
(polygonal) and flat
faces.
The lateral surface
area of a triangular
prism can
be calculated by
multiplying the
perimeter of the
base with the length
of the prism
Surface area of cube is the
sum of areas of all the faces
of cube, that covers it. The
formula for surface area is
equal to six times of square of
length of the sides of cube. It
is represented by 6a2, where
a is the side length of cube.
To find the surface area
of a cuboid which has 6
rectangular faces, add
the areas of all 6 faces.
Or, you can label the
length (l), width (w), and
height (h) of the cuboid
and use the
formula: surface area
(SA)=2lw+2lh+2hw
