### Abstract

Let *Q*(*x*) = *Q*(*x*_{1}, *x*_{2}, …, *x _{n}*) be a quadratic form with integer coefficients,

*p*be an odd prime and ||

*x*|| = max

*|*

_{i}*x*|. A solution of the congruence

_{i}*Q*(

*x*) ≡ 0 (mod

*p*

^{3}) is said to be a primitive solution if

*p*∤

*x*for some

_{i}*i*. We prove that if

*p*>

*A*; where

*A*= 5·2

^{41}; then this congruence has a primitive solution, with ||

*x*|| < 34

*p*

^{3/2}; 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.
