Solution:-
There is a mistake in the question. I think the surface area of the coloured paper is to be find out , which is not mentioned in the question.
Given : each side of the cube = 5 cm
Six cubes of edge 5 cm are placed side by side in a single row and glued together to form a cuboid.
Therefore, in the cuboid so formed,
Length = (6*5) = 30 cm (Length will increase 6 times), Breadth = 5 cm (will be the same) and Height = 5 cm (will be the same).
surface area of the cuboid = 2 (L*B + B*H + H*L)
= 2{(30 × 5) + (5 × 5) + (5 × 30)}
= 2(150 + 25 + 150)
= 2 × 325
= 650 cm²
Surface area of the cuboid or the surface area of the coloured paper used to cover the cuboid = 650 cm²
