The volume of a cube is 1728 cc. Find its surface.
Correct answer: A. 864 cm2
- A. 864 cm2
- B. 648 cm2
- C. 486 cm2
- D. 468 cm2
Explanation
For a cube, side^3 = 1728 cm3, so the side is 12 cm because 12 x 12 x 12 = 1728 cm3. Its surface area is 6 x (12 cm)^2 = 6 x 144 cm2 = 864 cm2. The likely wrong choice is 648 cm2, which comes from using an incorrect cube root or an incomplete surface-area calculation.

About Area and Volume
Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
