If the volume of a cube is 1728 cm3, then what is the total surface area of the cube?
Answer & explanation
Correct answer: option 3
We know that,
Volume of cube = Side3
Total surface area = 6(Side2)
We have,
Volume of a cube = 1728 cm3
Side of cube = a3 = (1728)1/3 = 12 cm
Total surface area = 6(Side2) = 6 × 144 = 864 cm2
