 <translate> The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet. The final answer: 270. <yor> Àwọn ìpele mẹ́wàá àkọ́kọ́ jẹ́ 10 * 12 = 120 ẹsẹ̀. Àwọn ìpele ogún - mẹ́wàá = mẹ́wàá ló kù.
