Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only) A right triangle is shown with one leg measuring 12, and the hypotenuse is labeled 13. An angle made with the leg measuring 12 and the hypotenuse is marked x degrees.

So we are asked to find the volume of the largest square prism that can fit inside a cube of given dimensions. One thing we have to remember that if given the volume of the cube we can easily get its dimensions. 

Next, we have to know that the volume of the pyramid is 1/3 of that of a rectangular prism. With this you should get 9.
