I think the the ribs are not a solid sheet because they need to be able to expand so the lungs can get an adequate amount of air in the lungs. The brain just needs to be protected and doesn’t need to expand so it’s a solid sheet. The skull seems to be the better protector at first because the ribs can break and puncture a lung, harming your breathing but if you do hit your head your brain can start swelling and the skull doesn’t allow any room for expansion. Head injuries are much more dangerous, especially if the brain starts swelling. Rib injuries seem much simpler to fix and less dangerous.

The amount of magnification you see through a microscope is extremely easy to calculate. You just multiply the power of each lens the image travels through together. So you have the equation
630 = 10 * x
where 630 is the total magnification and 10 is the magnification of the ocular lens. Now just solve for x by dividing both sides by 10
63 = x
So the objective lens has to have a power of 63x for your total magnification to be 630x</span>
