Cubing the Sphere - Calculator

Calculator for the edge length of a cube and the radius of a sphere, if both have the same surface area or volume. The cubing of the sphere is the three-dimensional equivalence to the squaring of the circle. Here also, an exact calculation is not possible, only an approximation at any accuracy. Please specify, if surface area or volume should be equal. Then enter one value, the other values will be calculated. Also pi can be entered or something like 2*pi.

equal surface areas equal volumes

Round to decimal places.

The unit is the same for edge length and radius. The surface area has this unit squared, the volume has this unit to the power of three. For example, length in centimeters, area in square centimeters, volume in cubic centimeters.

Example: cube and sphere with almost equal volumes. The edge length of the cube is 100 pixels, the sphere radius is 62 pixels, because there are no fractions of pixels.
