Explanation:
did you make a typo, or do you actually mean dm ?
1 dm = 10 cm
in any case, in a right prism object it does not matter what shape the bases are.
the volume is always
base area × height
so, if you did not make a typo, then
height = 2.3 dm = 23 cm
and the volume of the prism is
44 × 23 = 1012 cm³
but if you did make a typo and
height = 2.3 cm,
then the volume of the prism is
44 × 2.3 = 101.2 cm³
