Follow the given steps to use the calculator:
 Step 1: Select the name of the threedimensional figure for which you wish to find the surface area.
 Step 2: Enter the dimensions of the figure in the respective input boxes.
 Step 3: Click on "Calculate" to find the surface area and click on 'Reset' to clear the fields and enter the new values.
How to Find the Surface Area of a Threedimensional Figure?
Observe the following table to know the formulas used to find the surface area of different threedimensional figures.
Geometric Figure  Surface Area Formula  Dimensions 
Cube  6a^{2}  a = side of the cube 
Cuboid  2(LW + WH + LH)  L = length W = width H = height 
Cylinder  2пrh + 2пr^{2} 
r = radius h = height 
Cone  пr( r + l) 
r = radius l = slant height 
Sphere  4пr^{2}  r = radius 
Hemisphere  3пr^{2}  r = radius 
Now, let us look at the following examples to learn how to find the surface area of threedimensional figures.

Solved Example 1:
Find the surface area of a cuboid with length = 4 m, breadth (width) = 6 m, and height = 8 m.
Solution:
The given dimensions of the cuboid are L = 4 m, W = 6 m, and H = 8 m.
The surface area of a cuboid = 2(LH + WH + LW)
= 2[(4 × 8) + (6 × 8) + (4 × 6)]
= 2(32 + 48 + 24)
=2(104)
= 208 square meters
Therefore, the surface area of the cuboid is 208 square metres.

Solved Example 2:
Find the surface area of a sphere having a radius of 14 inches.
Solution:
The radius of the sphere is 14 inches.
The surface area of a sphere= 4пr^{2}
= 4 × п × 14^{2}
= 4 × 22/7 × 14 × 14
= 4 × 22 × 2 × 14
= 2464 square inches
Therefore, the surface area of the sphere is 2464 square inches.
Now, try the calculator to find the area of the following figures.
 A cube with each side of 12 units.
 A hemisphere with a radius of 9 units.
