If the height of multiple pyramids and rectangular prisms is the same, how many pyramids are needed to equal the volume of two rectangular prisms?

If the height of multiple pyramids and rectangular prisms is the same, how many pyramids are needed to equal the volume of two rectangular prisms?

• A. Four
• B. Five
• C. Six
• D. Seven

Answer: (C)

To determine how many pyramids are needed to match the volume of two rectangular prisms, it's important to understand the volume formulas for both shapes. The volume of a rectangular prism is calculated using the formula \( V = \text{length} \times \text{width} \times \text{height} \). For a pyramid, the volume is given by the formula \( V = \frac{1}{3} \times \text{base area} \times \text{height} \). Given that the height of the pyramids and rectangular prisms is the same, we can analyze their volumes in relation to one another. If we consider that the base area of the rectangular prism could be equal to the total base area of the pyramids, we can see that the volume of a pyramid is one-third that of a rectangular prism with the same base area and height. This means that to match the volume of one rectangular prism, it would take three pyramids. Therefore, to match the volume of two rectangular prisms, which together would have a total volume equivalent to \( 2 \times (\text{length} \times \text{width} \times \text{height}) \), we would need a
