 Question 235253: If the edge of a cube is tripled,what change takes place in the volume and in the surface area?Found 3 solutions by rfer, solver91311, stanbon:Answer by rfer(12731)   (Show Source): You can put this solution on YOUR website!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 Answer by solver91311(17077)   (Show Source): You can put this solution on YOUR website! 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. John Answer by stanbon(57984)   (Show Source): You can put this solution on YOUR website!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 ================================= Cheers Stan H.
