Yes. Calculate the height, then use the formula for the volume.

Explanation:

This is a square pyramid. The formula for its volume is
#V = (1/3)* (S^2*h)#
You can calculate the height, h, from the triangle formed by line from the center to the base, as shown. The angle is #60^o# and the length is ½ of the base, or 6 cm. The length of the opposite side is the tangent of #60^o# * 6 (tan = opp/adj). (10.4)
