To find the perpendicular height of a rectangular-based pyramid, we need to know the volume of the pyramid and the dimensions of its base.
The volume of a pyramid is given by the formula:
Volume = (1/3) * base area * height
In this case, we are given the volume of the pyramid as 294 cm³. Let's assume the base area of the pyramid is A cm², and the perpendicular height is h cm.
Since the base of the pyramid is rectangular, its base area is calculated as length * width. Let's say the length is L cm and the width is W cm.
So, we have:
Volume = (1/3) * A * h
294 = (1/3) * A * h
To find the perpendicular height (h), we need to know the base area (A) of the pyramid. Without that information, we cannot calculate the exact value of the perpendicular height.
