Question

A cuboid is of length 8 m, breadth 4 m and height 2 m. Calculate the lengths of all the diagonals.​

Answer 1

Answer:

$length \: = l \: = 8 \\ breadth \: = \: b = 4 \\ height \: = h = 2 \\ \: diagonal \: = d = \sqrt{ {l}^{2} + {b}^{2} + {h}^{2} } \\ = \sqrt{ {8}^{2} + {4}^{2} + {2}^{2} } \\ = \sqrt{64 + 16 + 4 } \\ = \sqrt{84} = 2 \sqrt{21}$
