V = Volume

A = Area of trangle

V = A * h

A = s ^ 2 * sqrt ( 3 ) / 4

where

s = length of equilateral triangle sides

A = 6 ^ 2 * sqrt ( 3 ) / 4

A = 36 * sqrt ( 3 ) / 4

A = 4 * 9 * sqrt ( 3 ) / 4

A = 9 * sqrt ( 3 )

A = 9 * 1.73025

A = 15.58845 mm ^ 2

V = A * h

V = 15.58845 * 8 .4

V = 130.94298 mm ^ 3

V = 130.9 mm ^ 3 rounded to the nearest tenth
