Calculate the volume of the triangular prism shown in the image.

Solution

To calculate the volume of the triangular prism, we follow these steps:

Step 1: Identify the components

The volume VV of a triangular prism is given by the formula: V=Base Area×Height of the prismV = \text{Base Area} \times \text{Height of the prism}

Base Area:

The base of the triangular prism is a triangle. The area AA of a triangle is: A=12×Base of the triangle×Height of the triangleA = \frac{1}{2} \times \text{Base of the triangle} \times \text{Height of the triangle}

From the diagram:

  • The base of the triangle = 8cm8 \, \text{cm}
  • The height of the triangle = 6cm6 \, \text{cm}

A=12×8×6=24cm2A = \frac{1}{2} \times 8 \times 6 = 24 \, \text{cm}^2

Height of the prism:

The length of the prism (depth) is 9cm9 \, \text{cm}.

Step 2: Calculate the volume

Substituting the values into the volume formula: V=Base Area×Height of the prism=24×9=216cm3V = \text{Base Area} \times \text{Height of the prism} = 24 \times 9 = 216 \, \text{cm}^3

Final Answer:

The volume of the triangular prism is: 216cm3\boxed{216 \, \text{cm}^3}
