Question

2. Find the length of the longest rod that can kept in the room of dimensions 5m, 4m and 3m.​

Answer 1

Answer:

5m

Step-by-step explanation:

they had asked the longest length

3<4<5

therefore 5m

Answer 2

Answer:

$here \: your \: answer$

Step-by-step explanation:

★Given

A room having dimension = 5m × 4m × 3m

Find the length of longest rod = ?

solution:

Since, the dimension of cuboid is given,

Length of longest rod is given by length of diagonal of cuboid.

Diagonal of cuboid ={l}^{2} + {b}^{2} + {h}^{2}

l2+b2+h2

Now,put the dimension is formula.

Diagonal of cuboid =

{5}^{2} + {4}^{2} + {3}^{2} } }

52+42

+32{25 + 16 + 9} }

25+16+9

{50} } 50

Length of longest rod ⟹ { 5 {2m}52m

hence, the length of longest rod kept in cuboidal room is {5 {2} }5

2m.
