The volume of a pyramid is given by the formula V = (1/3) * base area * height.
Since the base of the pyramid is a square with side length 10cm, the base area is 10cm * 10cm = 100cm^2.
Given that the volume of the pyramid is 700cm^3, we can plug in the values into the formula:
700 = (1/3) * 100 * height
700 = 100/3 * height
700 = 33.33 * height
height = 700 / 33.33
height ≈ 21cm
Therefore, the height of the pyramid is approximately 21cm.
Since the base of the pyramid is a square with side length 10cm, the base area is 10cm * 10cm = 100cm^2.
Given that the volume of the pyramid is 700cm^3, we can plug in the values into the formula:

height = 700 / 33.33
height ≈ 21cm
Therefore, the height of the pyramid is approximately 21cm.
