What is the radius of the largest sphere that can fit entirely inside a rectangular box with dimensions 4 cm and times 6 cm and times 10 cm?

The radius of the largest sphere that can fit entirely inside a rectangular box is determined by the smallest dimension of the box. In this case, the dimensions of the box are 4 cm, 6 cm, and 10 cm, with 4 cm being the smallest. Therefore, the radius of the largest sphere that can fit inside the box is half of the smallest dimension, which is 2 cm.
