Abstract: It is proved that under a certain condition on a separable metric space $ X$, each compact subset $ W$ of $ X \times Y$ with $ \dim W = \dim X + \dim Y$ contains a product $ X' \times Y' \subset W$ with $ \dim X' = \dim X$ and $ \dim Y' = \dim Y$. This condition is satisfied when $ X$ is a Euclidean space.
