What happens to the surface area and volume of a 3-D figure when the demensions change???

When the demensions of a figure are enlarged or they become smaller, the volume and surface area of the figure will change. For example, if you multiply the demensions of a figure by three, the volume of the figure will be three times bigger. If you devide the demensions by two, the volume of the figure will be two times smaller. The surface area will also become larger or smaller, but it is not as easy to figure out as the volume where it would just be three times bigger or two times smaller. A trick to find the surface area is to use what I call the "Y" trick. You draw a Y and then you put the demensions at the end of each line. In between 2 of the numbers, multiply them together. After that, multiply that number by 2. Do that all 3 times and then add all the answers together. This final answer will be your surface area. When you find out the surface area of the original figure... you need to find the surface area of the new demensions and compare your answers by deviding the surface area of the new figure by the surface area of the original figure. This would be how much bigger the new figure is compared to the original figure.You should do the oposite if you made the figure smaller.
