Answer 8

This is just the Pythagorean theorem. If you take a look at the cross section, one of the legs is the height \(9.1cm\), and the other leg is half the side, or \(12cm/2\). The slant height is just the hypotenuse:\[
x^2 = (9.1cm)^2+(12cm/2)^2\implies x = \sqrt{9.1^2+6^2}cm =\sqrt{118.81}cm =10.9cm
\]
