The volume of a triangular prism is the space it occupies in the three-dimensional plane. It is measured in cubic units such as m3, cm3, mm3, ft3.
The formula to calculate the volume of a triangular prism is given below:
In the above formula, the product of the half the base edge and the height is the base area of the prism. Therefore, we can also write the formula as:
Volume (V) = Base Area x Length
Let us solve some examples to understand the above concept better.
Find the volume of a right triangular prism whose base is 7 cm, the height is 8 cm, and the length is 25 cm.
As we know,
Volume (V) =
∴ V =
= 700 cm3
Find the volume of a triangular prism given in the figure.
As we know,
Volume (V) =
∴ V =
= 210 cm3
Finding the volume of a triangular prism when the BASE AREA is known
Find the volume of a triangular prism given in the figure whose base area is 256 in2.
As we know,
Volume (V) = Base Area × Length, here base area = 256 in2, length = 6.5 in
∴ V = 256 × 6.5
= 1664 in3
