Step-by-step explanation:
volume of a cube is 1331 cm³
let the side be 'a'
a³=1331cm³
a=³√1331cm³
a=³√11³cm³
a=11cm
T.S.A of cube =6a²sq.units
=6×(11cm)²
=6×121cm²
=726cm²
T.S.A of cube is 726cm²

Answer:
Let the side of the cube be 'a' cm
volume of cube = a³
a³ = 1331
a = √1331³
a = 11 cm
Surface area of a cube
= 6 a²
= 6 × 11²
= 6 × 121
= 726 cm²
Hence, the surface area of the cube is 726 cm².
