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 
. Now, we can once again use the pythagorean theorem to find RQ^2=2x^2+x^2=3x^2, so RQ=
=12, so x=
. To find the area of the shaded part, we multiply the length times width which gives us 
. So, the area of the shaded face of the cube is F: 48.

11. -(l/m)+c+1
12. (RK+T)/B
13. (c^2hm)/R
14. (ya-r)/(p^2*L)
Looking at the picture attached, you will notice that on one side, we have a side of length 7+5=12. Next, we have a side length of 4+5+2=11. Hence, as length*width=area for a rectangle, this is the overall area of the rectangle. Next, in the picture, there are clearly two sides taken out - a 2x5 as well as a 4x5 rectangle, which are subtracted from the total area, resulting in 11*12-2*5-4*5
