To find the volume of a cube from its surface area, first use the formula for surface area to find the length of one side of your cube. To do this, plug the surface area you're given into the formula, which is surface area = 6x^2, where x is the length of one side of the cube. Then, solve for x.
7f-10. Even though the “10 less” part comes first in this description, there needs to be a term that is subtracted by this first (7f). The product, this means multiplying, of 7 and f is 7f.
It is the last one. A closed circle means less than or equal to, so that crosses out the top two. The third says five is greater and we know that is not true because the line is decreasing in value. It must be the fourth.
