\[\boxed{\mathbf{4.152}}\]
Пояснение.
Решение.
\[\textbf{а)}\ a = 7\ см;b = 4\ см;c = 10\ см:\]
\[V = 7 \cdot 4 \cdot 10 = 280\ см^{3}\text{.\ }\]
\[\textbf{б)}\ a = 40\ дм;b = 30\ дм;\]
\[c = 40\ дм:\]
\[V = 40 \cdot 30 \cdot 40 = 48\ 000\ дм^{3} =\]
\[= 48\ м^{3}\text{.\ }\]
\[\textbf{в)}\ a = 4\ дм\ 2\ см = 42\ см;\]
\[b = 1\ дм\ 3\ см = 13\ см;\]
\[c = 80\ см:\]
\[V = 42 \cdot 13 \cdot 80 = 42 \cdot 1040 =\]
\[= 43\ 680\ см^{3}\text{.\ }\]
\[\textbf{г)}\ a = 9\ м = 90\ дм;b = 5\ дм;\]
\[c = 14\ м = 140\ дм:\]
\[V = 90 \cdot 5 \cdot 140 = 90 \cdot 700 =\]
\[= 63\ 000\ дм^{3} = 63\ м^{3}\text{.\ }\]
\[\textbf{д)}\ a = 13\ м = 130\ дм;b = 5\ дм;\]
\[c = 30\ см = 3\ дм:\]
\[V = 130 \cdot 5 \cdot 3 = 650 \cdot 3 =\]
\[= 1950\ дм^{3}\text{.\ }\]
