Question

Find the length of longest diagonal of a cuboid of dimensions 12 cm × 4 cm × 3 cm step by step on a paper.​

Answer 1

Answer:

A polygon has nsides. Two of its angles are right angles and each of the remaining angles is 144∘

Answer 2

13 cm

we know, d = √(l^2+b^3+h^2)

or d= √(12^2 ×4^2×3^2)

or,d= √169

or,d= 13
