To find the volume of each pris you multiply the measures

So

first prism


15\operatorname{cm}*12\operatorname{cm}*5\operatorname{cm}

then first blanck is 12

Second prism


5\operatorname{cm}*14\operatorname{cm}*4\operatorname{cm}

if we multiply 5 and 14


70sq\operatorname{cm}*4\operatorname{cm}

then second blanck is 70

Total volume


\begin{gathered} (15\operatorname{cm}*12\operatorname{cm}*5\operatorname{cm})+(70sq\operatorname{cm}*4\operatorname{cm}) \\ 900+280=1180 \end{gathered}

then last blanck is 1180cu cm
