100㎝＝10dm

10÷2＝5dm

3.14×5?=78.5dm?, covering an area of ??78.5 square decimeters.

Is the unit cubic meter of internal space correct? The quantity is relatively small, so it seems wrong to use cubic meters

48cm=4.8 decimeters

120cm=12 Decimeter

78.5×12+1/3×78.5×4.8

=942+125.6

=1067.6 cubic decimeter.

1067.6 cubic decimeter = 1.0676 cubic meter ≈ 1.07 cubic meter. The size of the interior space.
