Answer 2

The diagonal of the cuboid with dimensions 9cmx12cmx20cm is 25cm.

Given,

Dimensions of cuboid = 9cmx12cmx20cm

To Find,

The diagonal of the cuboid.

Solution,

We know that the Diagonal of the cuboid = √(l² + b² + h²)

⇒ diagonal = √(9² + 12² + 20²)

                   = √(81 + 144 + 400)

                   = √(625)

                   = ± 25

But, a diagonal is a length and length cannot be negative. So,

Diagonal of the cuboid = 25 cm.

Hence, the diagonal of the cuboid with dimensions 9cmx12cmx20cm is 25cm.
