Calculate the volume of a regular quadrilateral pyramid whose wall height is w = 12cm.

Correct answer:

V =  627.0694 cm3

Step-by-step explanation:

w=12 cm  a2 = (a/2)2 + w2 a2  (a/2)2 = w2 a2  a2/4 = w2 3/4a2= w2  a=w 2/3=12 2/3=8 3 cm13.8564 cm  h=w2(a/2)2=122(13.8564/2)2=4 6 cm9.798 cm  V=31 a2 h=31 13.85642 9.798=256 6=627.0694 cm3
