anybody mind helping me out with this?

Answer:
[tex]18\frac{3}{64} in^3[/tex]
Step-by-step explanation:
Volume is determined with the formula: [tex]V=lwh[/tex]
So, all you have to do is plug the values into the equation.
[tex]V=(\frac{7}{2} )(\frac{15}{8} )(\frac{11}{4} )\\V=\frac{1155}{64} \\V=18\frac{3}{64} in^3[/tex]
(I did make the values into fractions without the whole number just to make it easier.)
