Question

find the length of diagonal of the cuboid l=10cm,b=8cm,h=4cm​

Answer 1

Answer:

Diagnoal of the cube =13.38 cm

Step-by-step explanation:

Length of diagnoal of cuboid=

$\sqrt{ {l \:}^{2} \: + {b}^{2} \: + {h}^{2} }$

$\sqrt{ {10}^{2} \: + \: {8}^{2} \: + \: {4}^{2} }$

$\sqrt{100 \: + \: 64 \: \: + 16}$

$\sqrt{180}$

$6 \sqrt{5}$

Substitute √5 as 2.23

$6 \times 2.23$

$13.38 \: cm$
