Hi Carol, It looks like you have a pyramid constructed on a base which is a regular hexagon. Look at one of the triangles that form the sides.
Q is the midpoint of one of the sides of the base so angle PQR is a right triangle. Hence you can use Pythagoras' theorem to find the length PQ. Now look at the three dimensional pyramid again.
S is at the centre of the hexagonal base so PS is the height of the pyramid. Angle PSQ is a right angle so again you can use Pythagoras' theorem to find PS if you can first find SQ. SQ is half the width of the hexagon which you can find using our response to an earlier question. Penny
