Temple A enshrines a Bodhisattva with a height of 1 meter. The believers put gold on the Bodhisattva (paint the entire surface of the Bodhisattva with gold), and shared 3 kg of gold. Not to be outdone, Temple B also intends to enshrine a 10-meter-high golden body of a Bodhisattva with exactly the same shape. If the thickness of the gold painted on the bodies of Bodhisattvas is the same, how many kilograms of gold does Temple B need to use?
甲庙宇供奉一尊高为l公尺的菩萨，信众们为菩萨上金身(用黄金涂在菩萨像的全部表面)，共用了黄金3公斤．乙庙宇不甘示弱，也拟为其供奉的一尊高为10公尺，外形完全相似的菩萨上金身．若涂在菩萨身上黄金的厚度全部都相同，请问乙庙宇需用黄金多少公斤？
