D. 28/3 cm³
1) Given those dimensions, let's plug them into the following formula for the Volume of a Rectangular Prism, and simplify those fractions
8 and 4 by 4: 2, 1
10 and 5 by 5: 2,1
[tex]\begin{gathered} V=w\cdot l\cdot h \\ V=\frac{8}{5}\cdot\frac{10}{3}\cdot\frac{7}{4} \\ V=\frac{2}{1}\cdot\frac{2}{3}\cdot\frac{7}{1} \\ V=\frac{28}{3}\approx9.33cm^3 \end{gathered}[/tex]2) Hence the volume of that Prism is 28/3 cm³
