Answer:
volume of cube is l³
hence l³ = 64000 cm²
l = cube root of 64000
l = 40 cm³
now total surface area of the cube is 6l²
= 6× 40×40
= 6× 1600
= 9600 cm²

Answer:
Volume of cube = side³ = x³
=> x³ = 64000 cm³
=> x = ³√64000
=> x = 40 cm
Surface area of cube = 6 × side²
=> 6 × 40²
=> 6 × 1600
=> 9600 cm²
