Find the length of the diagonal of the prism.

12 cm 3 cm 4 cm

To find the length of the diagonal of the prism, we can use the Pythagorean theorem.

Let's call the length of the prism 12 cm, the width 3 cm, and the height 4 cm.

The length of the first diagonal is the hypotenuse of a right triangle with sides measuring 12 cm and 3 cm. By the Pythagorean theorem, we can calculate this diagonal as follows:

diagonal = √(12^2 + 3^2) = √(144 + 9) = √153 ≈ 12.37 cm

The length of the second diagonal is the hypotenuse of a right triangle with sides measuring 12 cm and 4 cm. By the Pythagorean theorem, we can calculate this diagonal as follows:

diagonal = √(12^2 + 4^2) = √(144 + 16) = √160 = 4√10 ≈ 12.65 cm

Therefore, the length of the diagonal of the prism is approximately 12.37 cm and 12.65 cm.
