A rectangular pyramid has a length of 7 and a width of 9 it's volume is 231 cubic centimeters use the formula for volume of pyramid to calculate the height of this pyramid
The volume of a rectangular pyramid is calculated using the formula:
Volume = (1/3) * base area * height
Given that the length of the pyramid is 7 and the width is 9, we can calculate the base area:
Base area = length * width
Base area = 7 * 9
Base area = 63 square centimeters
We are given that the volume is 231 cubic centimeters. Plugging in the known values into the formula, we can solve for the height:
231 = (1/3) * 63 * height
Multiplying both sides of the equation by 3:
693 = 63 * height
Dividing both sides of the equation by 63:
height = 693 / 63
height = 11
Therefore, the height of the rectangular pyramid is 11 centimeters.
