The figure shown is a trirectangular tetrahedron, a three-dimensional figure with four triangular faces, three of which are right triangles. A chemistry professor uses trirectangular tetrahedrons to create large scale models of various carbon-based molecules. The base of one of these tetrahedrons is an isosceles right triangle whose legs each have length 16 inches (in). The height of this tetrahedron is 9 in. Which of the following is closest to the volume of this tetrahedron, in pints? (Note: 1 pint = 0.5 quarts; use 1 quart = 57.75 ${\text{in}}^3$. The volume of a trirectangular tetrahedron is equal to $\frac{1}{3}Sh$, where $S$ is the area of its base and $h$ is its height.)
