8的立方在英语中可以表示为 "8 to the power of 3" 或者 "8 to the third power." 这两种表达方式的意思都是指 8 的 3 次方，即 8 的平方再乘以 8。
这种表达方式源自数学术语，在英语中常见于数学领域的讨论中。
一些英文例句和中文翻译如下：
The cube of 8 is equal to 8 to the power of 3, which is 512.
(8的立方等于8的三次方，即512。)
The volume of a cube with sides of 8 units is 8 to the third power, or 512 cubic units.
(一个边长为8单位的立方体的体积是8的三次方，即512立方单位。)
To find the cube root of a number, we can use the inverse operation of taking the number to the third power.
(要求一个数的立方根，我们可以使用反操作，即求该数的三次方。)
