The base is rectangular with $4 \times 9.5$ dimensions. There are three edges extending at a $90^\circ$ angle from the base with lengths $0.2, 0.5$ and $0.3$.

If you take your shape plus a mirror-reversed copy of it, they fit together along the oblique face to make a rectangular box with lengths $9.5\times 4 \times 0.5$. Since the original shape and its copy each have the same volume, that volume must be half the volume of the box.
