A rectangular pyramid has a length of 7 cm and a width of 9cm it’s volume is 231 cubic centimeters use the formula for the volume of the pyramid to calculate the height of this pyramid
The formula for the volume of a rectangular pyramid is given by V = (1/3) * (length) * (width) * (height).
Given:
Length = 7 cm
Width = 9 cm
Volume = 231 cm^3
Using the formula, we can substitute the given values and solve for the height:
231 cm^3 = (1/3) * 7 cm * 9 cm * height
Multiply both sides by 3 to remove the fraction:
693 cm^3 = 7 cm * 9 cm * height
Divide both sides by (7 cm * 9 cm):
693 cm^3 / (7 cm * 9 cm) = height
Height = 11 cm
Therefore, the height of the rectangular pyramid is 11 cm.
