first find the length of one side. because the sides are all equal, \[v=(side) \times (side) \times (side)\] so basically \[v=(side)^{3}\] so \[1331=(side)^{3}\] to get one side, find the cube root \[side=\sqrt[3]{1331} = 11\] so surface area will be \[(11 \times 11)\] for one face. but there are 6 faces so multiply your answer by 6
