Answer:
7
Explanation:
To find the width of the rectangular prism, we can use the formula for the volume of a rectangular prism:
Volume = length x width x height
We know the length is 4 inches and the height is 8 inches, and the volume is 224 cubic inches.
So:
224 = 4 x width x 8
Divide both sides by 32:
7 = width
Therefore, the width of the rectangular prism is 7 inches.
