6 cubes, each of edge 4 cm, are joined end to end. What is the total surface area of the resulting cuboid?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 496 cm2
New length of the cuboid(l) = 4 × 6 = 24 cm
Height(h) = breadth(b) = 4 cm
⇒ surface area of the cuboid = 2(lb + bh + hl) = 2 (96 + 16 + 96) = 416 cm2
