Calculating Volume of Prisms

This video tutorial covers the concept of volume for 3D figures, focusing on prisms. It explains the formulas for calculating the volume of rectangular and triangular prisms, highlighting the differences in their base area calculations. The tutorial includes two examples: one for a rectangular prism and another for a triangular prism, demonstrating the step-by-step process of finding their volumes.

What does the capital B in the volume formula represent?

• The height of the prism

• The perimeter of the base

• The area of the base

• The volume of the base

How is the volume of a triangular prism different from a rectangular prism in terms of calculation?

• A different formula is used

• The base area is divided by 2

• The base area is not required

• It is calculated without considering the height

Why is the base area divided by 2 in the calculation of a triangular prism's volume?

• It's a mistake in the formula

• Because the base is a triangle

• To simplify the calculation

• To double the volume
