3. The product of the areas of the six faces of a rectangular prism is 14641, then the volume of the rectangular prism is
【Analysis】Let's assume the length, width, and height of the rectangular prism are $a$, $b$, and $c$, respectively. Then the product of the areas of the six faces is: $(a b)^{2} \times(a c)^{2} \times(b c)^{2}=a^{4} \times b^{4} \times c^{4}=(a b c)^{4}=14641=11^{4}$, so $a b c=11$, which means the volume is 11
