The surface area of one cube is twice the surface area of a second cube. What is the ratio of their volumes?

Step-by-step explanation:

This question was linked from another one regarding the lengths of the cubes, you can find it here:

That question gave you the ratio of the lengths, which is . Now in geometry, a general rule about solids is that if they are similar, the ratio of their volumes is the cube of the ratio of their edges. In a cube's case, every single cube known to mankind is similar as all the edges are the same length.

So the ratio of volumes would be , which can be simplified as .

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
