Answer:

47.25 cubic centimetres

Explanation:

The volume of the prism is the product of its dimensions.

$3\operatorname{cm}*5(1)/(4)cm*3\operatorname{cm}$

Now,

multiplying 5 by 4/4 gives

$(4\cdot5)/(4)+(1)/(4)$
=(21)/(4)

Therefore,

$3\operatorname{cm}*5(1)/(4)cm*3\operatorname{cm}=3\operatorname{cm}*(21)/(4)cm*3\operatorname{cm}$
$=3\cdot(21)/(4)\cdot3\operatorname{cm}^3$
$=(3\cdot21\cdot3)/(4)cm^3$
=(189)/(4)cm^3

$=47.25\operatorname{cm}^3$
