英文和數學問題 英文&數學好的請進

While strolling through Tyrannia one bright sunny day, you came across a Grarrl egg. It was a perfect sphere. You placed it in a tub of water and found that it displaced exactly 280,000 cubic centimetres. However, it was floating on the water, and only 72% of the surface area of the egg was below the water line.

What was the total volume of the egg, in cubic centimetres? Please round to the nearest whole number.

請問答案是多少? (數學的) (專有名詞不用理會)

    Seventy-two percent of the egg is below the water line, which displaces 280,000 cm3 of water. So, the total volume of the egg is 288,000 / 72% = 400,000 cm3.

    蛋的體積中有72%在水面下,置換了280,000立方公分的水。因此,該蛋的體積為288,000 / 72% = 400,000立方公分。.

    另外還有一個問題,這是橢圓球體,還是普通圓球體?蛋應該是橢圓球體吧?

    當漫步通過Tyrannia 一個明亮的晴天, 您遇到了Grarrl 蛋。這是完善的球形。您安置了它在水和發現它確切地偏移了280,000 立方厘米。但是, 它浮動在水, 並且只72% 蛋的表面是在吃水線之下。

    什麼是蛋的總容量, 在立方厘米? 請在周圍對最近的整數。

    甚下自己想巴

    是 72% 的表面積在水下

    並不代表體積在水下

    這個比例會是1:1線性嗎???

    jyeh30, 你的回答我懷疑耶.

    表面積在水下的百分比會等同體積在水下的百分比嗎?

    如果是. 那jyeh30答對了. 問題沒有我想像的難

    否則我認為這個要用微積分

    :

    唉... 我微積分忘光了!!!!
