What will be the length of longest diagonal of the cuboid having length 13 cm width 11 cm and height 20 cm?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 26.27 cm.
Given that
The length of a cuboid (l) = 13 cm
The width of a cuboid (b) = 11 cm
The height of a cuboid (h) = 20 cm
Formula used
THe diagonal of a cuboid D = √(l² + b² + h²)
Calculation
D = √(13² + 11² + 20²) = √(169 + 121 + 400) = √690 = 26.27 cm
