To find the height of the rectangular pyramid, we can use the formula for the volume of a pyramid:

Volume = (1/3) * base area * height

Since the base of the pyramid is rectangular, the base area is determined by multiplying the length and width:

Base area = length * width

Given that the volume is 231 cubic inches, the base area is calculated as:

231 = (1/3) * (7 * 9) * height
231 = (63/3) * height
231 = 21 * height

Dividing both sides of the equation by 21:

231/21 = height
11 = height

Therefore, the height of the rectangular pyramid is 11 cm.
