Question

find length of diagonal of cuboid whose length is 12m , breadth is 8m and height is 3m .​

Answer 1

Answer:

14.7309198627  m is the answer

Step-by-step explanation:

diagonal of a cubiod =√l² + b² + h²

= √144+64+9

=√217

=14.7309198627 m

Answer 2

Answer :-

Given :-

• Length = 12 m
• Breadth = 8 m
• Height = 3 m

To Find :-

• Length of diagonal

Solution :-

$\bf Diagonal \: of \: cuboid = \sqrt{l^2 + b^2 + h^2}$

where

• l is length of cuboid
• b is breadth of cuboid
• h is height of cuboid

Here, we are given length, breadth and height and we are asked to find diagonal of cuboid. So, by simply substituting the value in formula, we can find diagonal :-

$\implies\sf D = \sqrt{12^2 + 8^2 + 3^2}$

$\implies\sf D = \sqrt{144 + 64 + 9}$

$\implies\sf D = \sqrt{217}$

$\boxed{\bf Diagonal \: of \: cuboid = \sqrt{217} \:m}$
