Answer :
TSA of a cube = 294 cm²
Let the side of the cube be s cm
TSA of a cube = 6s² sq.units
=> 294 = 6s²
=> 294 / 6 = s²
=> 49 = s²
=> s = √ 49
=> s = ± 7
=> s = 7 ( Neglecting - 7 as length can't be negative )
Volume of the cube = s³ cu.units = 7³ = 343 cm³
Therefore the volume of the cube is 343 cm³.
