What is the diameter and length of the sphere? In centimeters.
Let the side length of a regular cube be a.
Because a 3 = 8
So a=2
Just find the diagonal of the regular cube, which is the diameter of the sphere.
Here are two use of Pythagorean theorem,
The diagonal of the bottom surface is (√ 2) a.
The diagonal of the cube is (√3)a=2√3 cm.
√ is the root sign, and the top horizontal line cannot be displayed.
