Find the length of the diagonal of the cuboids whose dimensions are 3,4 and 5 cm​

(i) The given dimensions of the cuboid are 2, 3 and 4 cm. Hence, the length of the diagonal of the cuboid whose dimensions are 2, 3 and 4 cm is equal to √29cm. (ii) The given dimensions of the cuboid are 3, 4 and 5 cm. ⇒d=√9+16+25=√50cm.
