Answer with explanation:
Let L units be the Length of Original rectangular prism, B units be the Breadth of Original rectangular prism, and H units be the Height of Original rectangular prism.
→Volume of Original Prism =Length ×Breadth× Height
= L B H (units)³
Dimension of New Rectangular Prism
New Length of Prism = 3 L units
New Breadth of Prism = 2 B units
New Height of Prism = 2 H units
→Volume of the New Prism = New Length × New Breadth × New Height
= 3 L × 2 B × 2 H
=12 L B H (units )³
=12 × Volume of the Original Prism
Option B.→ twelve times the original volume
