Answer:
So to get the length of the side of this cube you have to find the cube root of 216 . And that is 6.( Use the trick that you can learn on you tube to find out the cube root .)
So a cube has equal lengths width and heights . This means that each of the cube's six faces is a square . The total surface area is therefore six times the area of one face.. to work out one face area .you multiply one width by height . . In this case it is 6 X 6 = 36
36 cm squared. Is one cube face . Multiply this by 6 for each of the 6 faces. 36X6 = 216 cm2 . In this case volume is equal to surface area of once face x 6 .
