Question

find the length of the longest pole that can be put in a room of dimensions 10metre by 10 metre by 5 metre​

Answer 1

Answer:

5 metre

Step-by-step explanation:

Answer 2

Answer:

The length of the longest pole = 15 m.

Step-by-step explanation:

The length of the longest pole = The length of the diagonal of the room(cuboid)

Diagonal of a cuboid = $\sqrt{l^{2}+b^{2}+h^{2} }$ unit.

i.e., The length of the pole = $\sqrt{10^{2}+10^{2}+5^{2}}$ m

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

                                            = $\sqrt{225}$ m

                                            = 15 m.
