Where, a is the side length of the square.
Putting in the above formula, we get
It is given that point B is the center of the base. It means point B bisect each diagonal of a base. So,
In a right angle triangle,
In triangle ABC,
Round the value to the nearest integer.
The height of the pyramid is about 7 cm. Therefore, the correct option is A.
