how to find volume of a prism

Solution

To find the volume of a prism, you use the following general formula:

Volume=Base Area×Height\text{Volume} = \text{Base Area} \times \text{Height}

Where:

  • Base Area is the area of one of the two parallel faces (called the bases) of the prism.
  • Height is the perpendicular distance between the two bases.

Steps to find the volume of a prism:

  1. Determine the shape of the base: It can be a triangle, rectangle, or any polygon. The method to calculate the base area will depend on its shape.

  2. Calculate the area of the base: Use the appropriate formula for the base's shape. For example:

    • If the base is a rectangle: Base Area=length×width\text{Base Area} = \text{length} \times \text{width}
    • If the base is a triangle: Base Area=12×base×height\text{Base Area} = \frac{1}{2} \times \text{base} \times \text{height}
  3. Find the height of the prism (the distance between the two parallel bases).

  4. Multiply the base area by the height of the prism to get the volume.

Example:

For a rectangular prism with a base area of 15 square units and a height of 10 units: Volume=15×10=150cubic units\text{Volume} = 15 \times 10 = 150 \, \text{cubic units}
