Given length l = 12 m
breadth b = 9 m and height h = 8 m
Longest rod that can be placed in a room is nothing but its diagonal.
Length of diagonal of a cuboid = √(l2 + b2 + h2)
Length of longest rod = √(122 + 92 + 82) m
= √(144 + 81 + 64) m
= √289 m
= 17 m
Thus the length of the longest rod is 17 m
breadth b = 9 m and height h = 8 m

3+4+5 = 12
one side is 3/12 * 96cm = 24cm (the base)
another side is 4/12 * 96cm = 36cm (the height)
the other side is the hypotenuse, and we don't need to calculate it to find the area
The area is 1/2 * base * height = 384 square

Answer:
17m
Step-by-step explanation:
Given
length l = 12 m
breadth b = 9 m
height h = 8 m
Longest rod that can be placed in a room is nothing but its diagonal.
Length of diagonal of a cuboid = √(l2 + b2 + h2)
Length of longest rod = √(122 + 92 + 82) m
= √(144 + 81 + 64) m
= √289 m
= 17 m
hence the length of the longest rod is 17 m
