If there is a picture, it would be very useful, because the height and slant height are two sides of a right triangle.
A good picture would show that the bottom side of this triangle is half the side length of the square. This is a leg of the right triangle: A=12'
The hypotenuse of the triangle is the slant height: C=46'
The "unknown" height is the other leg of the right triangle: B=?
The pythagorean theorem A2+B2=C2 gives 144sqft+B2=2116sqft
Solving for B gives B=44.4'
Therefore, the height of the pyramid is 44.4 feet.

You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.

Volume = 50 in3
It is 448 square cm.
To find the perpendicular height of a square pyramid, first compute for the volume of the pyramid. Then divide the volume by the area of the base to find pyramid's height.
72 cm square.
Volume of a pyramid is (1/3)*(area of base)*(height) = (1/3)*(6 in)2*(8 in) = 96 in3
