Question

find the length of a diagonal of a cuboid of dimensions 10 metre by 10meter by 5 metre​

Answer 1

$diagonal = \sqrt{ {l}^{2} + {b}^{2} + {h}^{2} }$

$diagonal = \sqrt{ {10}^{2} + {10}^{2} + {5}^{2} }$

$diagonal = \sqrt{100 + 100 + 25}$

$diagonal = \sqrt{225}$

$diagonal = 15$

Thnx✌️✌️
