Answer:
3 ft
Explanation:
(I assumed that this was a rectangular prism based on the dimensions given, but do correct me if I assumed incorrectly.)
The formula for finding the volume of a rectangular prism is:
In this case, we already know that the volume of the prism is 24, so we can plug 24 in for V:
We also already know the height and the length because they gave it to us, so we can plug it in as follows:
Then we can multiply 2 and 4 on the right side:
Then, to get the w alone, we can divide by 8 on both sides:
Now that gives us that the width of the rectangular prism is 3ft.
