Correct Answer :

Option A

676

Solution :

The correct option is 676.

Step 1: Find the side length of the cube.
Let the side length of the cube be a cm.
The volume of a cube is given by the formula:

Volume=a3

Given that the volume of the cube is 2197 cm3:

a3=2197

Taking the cube root on both sides:

a=21973

Since 133=2197, we find:

a=13 cm

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:

LSA=4a2

Substitute a=13 into the formula:

LSA=4×(13)2

LSA=4×169

LSA=676 cm2

Thus, the lateral surface area of the cube is 676 cm2.
