Triangular pyramid

A regular tetrahedron is a triangular pyramid whose base and walls are identical equilateral triangles. Calculate the height of this body if the edge length is a = 8 cm

Correct answer:

h =  6.532 cm

Step-by-step explanation:

a=8 cm  a2=h12+(a/2)2 h1=a2(a/2)2=82(8/2)2=4 3 cm6.9282 cm  h2+(2/3 h1)2=a2  h=a2(2/3 h1)2=82(2/3 6.9282)2=6.532 cm
