Rectangular prism volume formula
[tex]V=whl[/tex]
where w is the width, h is the height, and l is the length of the prism.
Substituting with w = 1.1 in, h = 2.5 in (same as 2 and a half inches), and l = 9.75 in, the volume of the prism is:
[tex]\begin{gathered} V=1.1\cdot2.5\cdot9.75 \\ V=26.8125\text{ in}^3\text{ } \end{gathered}[/tex]
