3^3=27
9^3=729
The volume increases by 27 times
3*3=9*6=54
9*9=81*6=486
The surface area increases by 9 times

Let represent the measure of one edge of a cube. The volume is then and the surface area is . If you triple the measure of the edges, then each edge would measure , so the volume would be which is 27 times larger than the original cube. The surface area of the larger cube would be which is 9 times larger than the original cube.

If the edge of a cube is tripled,what change takes place in the volume and in the surface area?
--------------------
Volume Formula:
V = s^3
-------------------------------
After tripling the side:
V = (3s)^3 = 27s^3
-------------------------------
Surface Area
S = 6s^2
---------------------
After tripling the side:
S = 6(3s)^2 = 6*9s^2 = 54s^2
