8.5 units³
Explanation:
The volume can be found as the product of the two given values.
In fact, for any right angled 3D figure, we can find its volume as area of one face times the height or length.
Thus, we get volume as
V = 4 × 17/8 (converting 2 1/8)
V = 17/2 units³ or 8.5 units³
Hope this helps!
