Answer:

V=(3W^3+12W^2)\ units^3

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

V=LWH -----> equation A

where

L is the length

W is the width

H is the height

we know that

L=3W -----> equation B

H=W+4 ----> equation C

substitute equation B and equation C in equation A

V=(3W)(W)(W+4)

Apply distributive property

V=(3W^3+12W^2)\ units^3
