Question

Find he length (in metre) of the longest rod that can be put in a room of dimension 10 m X 10 m X 5m.​

Answer 1

The length of the longest rod is 500m3

Answer 2

The longest length of rod = hypotenuse

length = 10m

breath = 10m

so, h square = r square + p square

h square = 10 square + 10 square

h square = 100 + 100

h square = 200

h = √200

h = 10√2
