There is a quadrangular pyramid with the sum of the lengths of its edges being 14.8 meters (m). Find the length of one edge of this quadrangular pyramid when all the edge lengths are the same.
14.8 4 2 [OP_MUL] [OP_DIV]
var_a = 14.8
var_b = 4
var_c = 2
var_d = var_b * var_c
var_e = var_a / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
