The Hinode satellite weighs approximately 700 kg (dry) and carries 170 kg of gas for its steering thrusters, which help to maintain the satellite in a polar, sun-synchronous orbit for up to two years. The satellite has two solar panels (blue) that produce all the spacecraft's power. The panels are 4 meters long and 1 meter wide and are covered on both sides by solar cells.

what is the total area of the solar panels covered by solar cells in square centimeters? ​
