The volume of a cube is 2197 cm3. What is its lateral surface area (in cm2) ?
Correct Answer :
676
Solution :
The correct option is 676.
Step 1: Find the side length of the cube.
Let the side length of the cube be cm.
The volume of a cube is given by the formula:
Given that the volume of the cube is 2197 cm3:
Taking the cube root on both sides:
Since , we find:
Step 2: Calculate the lateral surface area of the cube.
The lateral surface area (LSA) of a cube consists of the area of its 4 side faces and is given by the formula:
Substitute into the formula:
Thus, the lateral surface area of the cube is 676 cm2.
