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.

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!!!!
