The difference between the total surface area and the lateral surface area of a cube of side 12 cm is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 288 cm2.
The total surface area of the cube = 6a2
The lateral surface area of the cube = 4a2
Side of the cube a = 12 cm
Difference = 6a2- 4a2 = 2a2
= 2 × 122
= 288 cm2
