Four identical blocks of wood are placed touching a table in the positions shown.
How high is the table?
let the height of the table be $\displaystyle H$, and the height and width of theOriginally Posted by Natasha1
blocks be $\displaystyle h$ and $\displaystyle w$ respectivly.
Then we have:
$\displaystyle
96=H+h-w
$
and
$\displaystyle
84=H-h+w
$
Now add the two equations:
$\displaystyle
180=2H
$
so:
$\displaystyle
H=90
