Question

A rectangular pyramid has a volume of 10 cm3
. What is the volume of a rectangular prism given it has a congruent base and height to the pyramid?(1 point)
cm3

1 answer

The volume of a rectangular prism is calculated using the formula:

\[ \text{Volume} = \text{Base Area} \times \text{Height} \]

For a pyramid, the volume is given by:

\[ \text{Volume of Pyramid} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \]

Given that the volume of the rectangular pyramid is 10 cm³, we can denote the base area as \( B \) and the height as \( h \). Therefore, we have:

\[ 10 = \frac{1}{3} \times B \times h \]

To find the volume of the rectangular prism with the same base area and height, we can rearrange the pyramid's volume formula. Specifically, the volume of the prism is given by:

\[ \text{Volume of Prism} = B \times h \]

To relate this back to the pyramid's volume, we can rearrange the equation from the pyramid's volume:

\[ B \times h = 3 \times 10 = 30 , \text{cm}^3 \]

Thus, the volume of the rectangular prism is:

\[ \text{Volume of Prism} = 30 , \text{cm}^3 \]

Therefore, the volume of the rectangular prism is 30 cm³.
