1st one- |dw:1456507656120:dw|
1st you see that triangle ABC its a right triangle and we can find the diagonal AC
by pythagorus theorem
it will be 
$AC^2=AB^2+BC^2$
$AC^2=l^2+w^2$
$AC= \sqrt{l^2+w^2}$

now you see that triangle ACD
apply pythagorus theorem again
$AD^2=AC^2+CD^2$

AD is the diagonal which we need

$AD^2=l^2+w^2+h^2$
