Please calculate the height of a regular hexagonal pyramid with a base edge of 5cm and a wall height of w = 20cm. Please sketch a picture.

Correct answer:

h =  19.5256 cm

Step-by-step explanation:

a=5 cm w=20 cm r=a=5 cm  s2 = (a/2)2 + w2 s=(a/2)2+w2=(5/2)2+20220.1556 cm  s2 = r2 + h2  h=s2r2=20.1556252=19.5256 cm
