Answer:

F: 48

Step-by-step explanation:

Let x be the length of the side of the cube. RQ can be expressed as a triangle consisting of a diagonal of a face of the cube and the side length x. By the pythagorean theorem, we know that a^2+b^2=c^2. So, we can express the diagonal as x^2+x^2=c^2, giving us the value of c to be $x\sqrt{2}$ . Now, we can once again use the pythagorean theorem to find RQ^2=2x^2+x^2=3x^2, so RQ= $x\sqrt{3}$ =12, so x= $4\sqrt{3}$ . To find the area of the shaded part, we multiply the length times width which gives us $(4\sqrt{3})^2=48$ . So, the area of the shaded face of the cube is F: 48.
