Use the model for the base of a triangular prism and triangular pyramid if the height are both 9 cm
Both the base of a triangular prism and a triangular pyramid have a triangular shape, and their heights are both 9 cm. The only difference between the two shapes is that a prism has two parallel and congruent triangular bases, while a pyramid has one triangular base and triangular sides that meet at a single point.
To calculate the volume of the triangular prism, you would use the formula:
Volume = 1/2 * base area * height
To calculate the volume of the triangular pyramid, you would use the formula:
Volume = 1/3 * base area * height
In this case, both formulas would result in the same volume for the triangular prism and triangular pyramid, as they both have the same base area and height.
