text: Below is an context that describes a sql query, paired with an question that provides further information. Write an answer that appropriately completes the request.  # noqa: E501
  ### Context:
  CREATE TABLE table_name_30 (_inches VARCHAR, skin_depth INTEGER, resistivity__10_−6_ohm_inches_ VARCHAR, relative_permeability VARCHAR)
  ### Question:
  What is the sum of skin depth with a resistivity of 1.12 and a relative permeability larger than 1?
  ### Answer:
  SELECT SUM(skin_depth), _inches FROM table_name_30 WHERE resistivity__10_−6_ohm_inches_ = 1.12 AND relative_permeability > 1
