answer :-
Option a , 288 m^3
Volume of rectangular prism is given by the formula, V = length x breadth x height.
=> V = l x b x h
Given ,
Length of rectangular prism = 12m
Breadth of rectangular prism = 8m
Height of rectangular prism = 3 m
Volume of rectangular prism = 12 x 8 x 3
=> V = [tex]\fbox{288 m^{3}}[/tex]
[tex]288 m^{3}[/tex] is the answer.
