Answer:
3840 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is 960 cubic inches
Let the dimensions be lXwXh,
l=length of the base
w=width of the base
h=height of the base
The volume, lwh=960 cubic inches

Volume of the new rectangular prism=2l X 2w X h =4lwh
=4 X 960 =3840 cubic inches
