### Abstract

Let Q(x) = Q(x1, x2, …, xn) be a quadratic form with integer coefficients, p be an odd prime and ||x|| = maxi|xi|. A solution of the congruence Q(x) ≡ 0 (mod p3) is said to be a primitive solution if pxi for some i. We prove that if p > A; where A = 5·241; then this congruence has a primitive solution, with ||x|| < 34p3/2; provided that n ≥ 6 is even and Q is nonsinqular (mod p). Moreover, similar result is proven for cube boxes centered at the origin with edges of arbitrary lengths. These two results are extension of the quadratic forms problems.
