Are the cherubim of 1 Kings 6:23-27 really with wingspans of 15 feet?

Referring to this passage: **1 Kings 6:23-27,** > 23 Inside the inner sanctuary he made two cherubim of olive wood, each > ten cubits high. 24 One wing of the cherub was five cubits, and the other > wing of the cherub five cubits: ten cubits from the tip of one wing to > the tip of the other. 25 And the other cherub was ten cubits; both > cherubim were of the same size and shape. 26 The height of one cherub was > ten cubits, and so was the other cherub. 27 Then he set the cherubim > inside the inner room; and they stretched out the wings of the > cherubim so that the wing of the one touched one wall, and the wing of > the other cherub touched the other wall. And their wings touched each > other in the middle of the room. A cubit is said to be 18-20.4 inches. 10 cubits at 18" would be 15 feet. 10 cubits at 20.4" would be 17 feet. In numerous pictures of the cherubim on the internet , they are usually shown to be small, fitting entirely within the bounds of the dimensions of the ark, which is 2 cubits by 1.5 cubits. The cherubim should be 15 feet tall, minimum! The Most Holy Place was a 20-cubit cube in shape (1 Kings 6:16-20 ). According to verse 27, the wings touched the wall on either side, yet the dimensions given in verses 24-25 indicate the wingspans are less than that size. (Still, at a 10-cubit wingspan, that would be HEAVY to carry!) The directions for the cherubs indicate only two wings apiece. If the wings were stretched out to touch the walls, how do they also touch each other "in the middle of the room"? I wonder if this touching is so because the cherubim are in the middle of the room, so if the wings project out their backs, that's also where they are touching each other per cherubim. How do the wings touch each end of the Most Holy Place walls that are 20 cubits apart?
