Volume of pyramid with rhombus base
Explanation:
Volume of pyramid is
This formula remains same for all pyramids.
For a cone, it is
Likewise, area of a pyramid with rhombus base is
= (Base area * height).
Area of Rhombus is given by
Volume of a prism with rhombus base is
Explanation:
Volume of any prism is area of its base multiplied by its height.
As base is rhombus in shape and its area is half the product of its diagonals, if its diagonals are
Hence, if height of a prism with rhombus base is
Hence, volume of a prism with rhombus base is
See the example.
Explanation:
In general, the volume of a prism can be calculated by the formula
Then, you have to calculate the area of the rhombus.
If the lengths of two diagonals in a rhombus are
[Example1] Find the area of the rhombus below.
The lengths of the two diagonals are
Its area is
[Example2] Evaluate the volume of a prism which has a base same as [Example1] and height
Area of base is
Therefore, the volume is
