A rectangular prism has a length of 3, a width of 4, and a height of 12. What is the distance between two opposite corners of the prism?

The distance between two opposite corners is 17.

A rectangular prism has a length of 3, a width of 4, and a height of 12. What is the distance (D) between two opposite corners of the prism?

The diagonal of the base: d = sqrt( 3^{2} + 4^{2} ) = 5

The distance D = sqrt( 5^{2} + 12^{2} ) = 13
