Question

Find the diagonal of a cuboid whose length 12 cm and breadth 10 cm and height 8cm
​

Answer 1

length (l) =12cm

breadth (b) =10cm

height (h) =8cm

diagonal =

$\sqrt{l {}^{2} + b {}^{2} + h { }^{2} }$

=√12^2 +10^2+8^2

=√144+100+64

=√2*2*3*2*2*3*2*5*2*5*2*2*2*2*2*2

=2*2*2*2*2*2*3*5

=960
