A square pyramid and a cube have the same bases and volumes. How are their heights related?

Volume of square pyramid = a²*h/3, bases are the same so area of a base = a²

Volume of cube=a²*a, same base so area of a base of a cube = a²,

because all edges of a cube are equal, so height of a cube = a

Volume of the square pyramid=Volume the a cube

a²*h/3=a²*a

h/3=a

h=3a

the height of the pyramid is 3 times the height of the cube
