The new volume is Nine time the original volume
Step-by-step explanation:
Let the length be 'l'
Let the height be 'h'
Let the width be 'w'
Volume of a rectangular prism= l x w x h
New length = 1.5l
New width = 2w
New height= 3h
New volume= (1.5l) x (2w) x (3h)
= 9 (l x w x h)
New volume= 9 ( original volume)
The new volume is 9 time the original volume
