the volume of a pyramid is

[tex]V=\frac{1}{3}Ah[/tex]

where A is the area of the basis and h is the height of the pyramid.

[tex]A=\frac{12.3\text{ in }\times10\text{ in}}{2}=61.5in^2[/tex]

Then the volume is

[tex]\begin{gathered} V=\frac{1}{3}(61.5in^2)(17.6in) \\ =360.8in^3 \end{gathered}[/tex]

Then rounding the number, the answer is B).
