volume of cube = 1726 cm
∴ (a)³ = 1726 { a is edge of cube}
a = 11.9953..... = 12 cm approx
total surface area of cube = 6(a)²
= 6(12)²
= 6*144
= 864 cm²
∴ (a)³ = 1726 { a is edge of cube}
a = 11.9953..... = 12 cm approx
total surface area of cube = 6(a)²
= 6(12)²
= 6*144
= 864 cm²

Let's consider the sides of a cube = x
According the question the volume of a cube is 1726 cm(cube)
∴ x³ = 1726 cm³
x =∛1726cm³
= 11.9953.
= 12 cm ( approx)
Side will be 12cm.
Total surface area of a cube = 6 x side²
∴ Total surface area of a cube = 6 x (12 cm)²
= 6 × 144 cm²
= 864cm²
Hence the total surface area of the cube 864cm²
Ans :- Total surface area of the cube 864cm²
