Let In < alpha < p <= n and let f is an element of W-1.P(R-n, R-k) be p-quasicontinuous. We find an optimal value of beta(n, m, p, alpha) such that for H-beta a.e. y is an element of (0. 1)(n-m) the Hausdorff dimension of f((0, 1)(m) x {y}) is at most alpha. We construct an example to show that the value of the optimal 11 does not increase once p goes below the critical case p < alpha.
