There is a quadrangular pyramid whose edges have the same length. If the sum of the lengths of the edges is 14.8 meters (m), how many meters (m) is the length of one edge?
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)))
