$\large\red\checkmark$ Option [B] 40 sq. cm.

Explanation :-

Given :

• Length of Cuboid = 3 cm.
• Breadth of Cuboid = 2 cm.
• Height of Cuboid = 4 cm.

To Find :

• L.S.A of Cuboid.

Solution :

We know that,

L.S.A. of Cuboid = 2(l + b)h.

➨ L.S.A of Cuboid = 2(3 + 2)4.

➨ L.S.A of Cuboid = (2)(5)(4).

➨ L.S.A of Cuboid = 10 × 4.

➨ L.S.A of Cuboid = 40 sq. cm.

Therefore, Answer = Option [B] 40 sq. cm.

Extra Shots :-

• T.S.A of Cuboid = 2(lb + bh + hl).

• Volume of Cuboid = l × b × h.

• L.S.A of Cuboid = 2(l + b)h.
