Kya pata mujhko maloom nahi hai

Answer 2

Answer:

The correct answer is option (4). 6

Step-by-step explanation:

From the given informations,

we get there are 4*3*5 = 60 small cubes of side 1cm each.

All the faces of cuboid are coloured.

The cubes in which no colours are inside the cuboid

To find the number of cube inside

The diamensios of cuboid = 4x3x5

The number of cubes inside = (4-2)*(3-2)*(5-2) = 2*1*3 = 6 cubes

Therefore the correct answer is option(4). 6
