height is 8 m. Then find the length of diagonal
of cuboid.​

Answer 1

Step-by-step explanation:

hello mate

Here is your answer

Here Length of the diagonal=

√Length *Breadth*Height

=√12*9*8

=√3*2*2*3*3*2*2*2

=√3*3*3*2*2*2*2*2

=3*2*2√3*2

=12√6 cm

Answer 2

Answer:

Length =12m

Breadth =9m

height =8m

diagonal of cuboid=》

$\sqrt{l {}^{2} + b {}^{2} + c {}^{2} } \\ = \sqrt{12 {}^{2} + 9 {}^{2} + 8 {}^{2} } \\ = \sqrt{144 + 81 + 64} \\ = \sqrt{289} \\ = 17$

Thus; length of diagonal is 17m
