The image above is an ellipsoid. To calculate the volume of an ellipsoid, three essential parameters are needed and these parameters are axis (a), axis (b), and axis (c).
The formula for calculating the volume of an ellipsoid:
V = 4πabc ⁄ 3
Where;
V = Volume of the ellipsoid
a = Axis of the ellipsoid
b = Axis of the ellipsoid
c = Axis of the ellipsoid
Let’s solve an example;
Given that the axis of the ellipsoid (a) is 9 cm and axis of the ellipsoid (b) is 11 cm with the axis (c) of 14 cm. Find the volume of the ellipsoid?
This implies that;
a = Axis of the ellipsoid = 9 cm
b = Axis of the ellipsoid = 11 cm
c = Axis of the ellipsoid = 14 cm
V = 4πabc ⁄ 3
V = 4π(9 x 11 x 14) ⁄ 3
Then, V = 4π(1386) ⁄ 3
V = (12.56)(1386) / 3
V = (17416.98967) / 3
So, V = 5805.66
Therefore, the volume of the ellipsoid is 5805.66 cm3.
Calculating the Axis (a) of an Ellipsoid using the Volume of the Ellipsoid, Axis (b) of the Ellipsoid and Axis (c) of the Ellipsoid
a = V3 / 4πbc
Where;
a = Axis of the ellipsoid
V = Volume of the ellipsoid
b = Axis of the ellipsoid
c = Axis of the ellipsoid
Let’s solve an example;
Find the axis (a) of an ellipsoid when the volume of the ellipsoid is 280 cm3 with an axis (b) of 18 cm and axis (c) of 8 cm.
This implies that;
V = Volume of the ellipsoid = 280 cm3
b = Axis of the ellipsoid = 18 cm
c = Axis of the ellipsoid = 8 cm
a = V3 / 4πbc
a = 280 x 3 / (12.566)(18 x 8)
So, a = 840 / (12.566)(144)
a = 840 / 1809.504
a = 0.46

Calculating the Axis (b) of an Ellipsoid using the Volume of the Ellipsoid, Axis (a) of the Ellipsoid, and Axis (c) of the Ellipsoid
b = V3 / 4πac
Where;
b = Axis of the ellipsoid
V = Volume of the ellipsoid
a = Axis of the ellipsoid
c = Axis of the ellipsoid
Let’s solve an example;
Find the axis (b) of an ellipsoid when the volume of the ellipsoid is 320 cm3 with an axis (a) of 19 cm and axis (c) of 7 cm.
This implies that;
V = Volume of the ellipsoid = 320 cm3
a = Axis of the ellipsoid = 19 cm
c = Axis of the ellipsoid = 7 cm
b = V3 / 4πac
b = 320 x 3 / (12.566)(19 x 7)
Then, b = 960 / (12.566)(133)
b = 960 / 1671.278
b = 0.574
Therefore, the axis (b) of the ellipsoid is 0.574 cm.
Calculating the Axis (c) of an Ellipsoid using the Volume of the Ellipsoid, Axis (a) of the Ellipsoid, and Axis (b) of the Ellipsoid
c = V3 / 4πab
Where;
c = Axis of the ellipsoid
V = Volume of the ellipsoid
a = Axis of the ellipsoid
b = Axis of the ellipsoid
Let’s solve an example;
Find the axis (c) of an ellipsoid when the volume of the ellipsoid is 480 cm3 with an axis (a) of 22 cm and axis (b) of 11 cm.
This implies that;
V = Volume of the ellipsoid = 480 cm3
a = Axis of the ellipsoid = 22 cm
b = Axis of the ellipsoid = 11 cm
c = V3 / 4πab
c = 480 x 3 / (12.566)(22 x 11)
That is, c = 1440 / (12.566)(242)
c = 1440 / 3040.972
c = 0.474
Therefore, the axis (c) of the ellipsoid is 0.474 cm.
And that’s how you calculate the axis and volume of an ellipsoid!
