Answer:
Horizontal component = 9.6
Step-by-step explanation:
Recall that the horizontal component is given by the cosine projection;

which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:

And rounding to the nearest tenth as requested, we have:

Add 8 to both sides
2x = 28
Divide 2 to both sides
Solution: x = 14
Original cube side length is s = 4 inches, so the vol. is 4^3 in^3, or 64 in^3 = s^3.
If we double the original side length, we get S = 2s, and the new volume
is S^3 = (2s)^3 = 8s^3 = 8(64 in^3) = 512 in^3.
Answer: the new cube has a volume 8 times greater than the original cube has.
