There is a rectangular parallelepiped-shaped lake with a length of 9 meters (m) wide and a length of 7 meters (m) long. If the volume of this lake is 315 square centimeters (cm2), how deep is this lake in centimeters (cm)?
315 9 [OP_DIV] 7 [OP_DIV]
var_a = 315
var_b = 9
var_c = var_a / var_b
var_d = 7
var_e = var_c / var_d
print(int(var_e))
