Gina has one-third scale model of a three-dimensional solid, meaning that all lengths of the model are 1/3 of the corresponding lengths in the full-size solid. If the volume of
Gina’s model is 20 cubic inches, what is the volume of the full-sized solid?

volume is 540 inches^3

Step-by-step explanation:

The computation of the volume of the full sized solid is given below:

The length would be

And, the volume is

As the volume is given 20 cubic inches

So,

hence, volume is 540 inches^3

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
