Answer:
1. The height if the box is x.
2. The length of the box is 8 - 2x
3. The width of the box is 12 - 2x
4. The volume of the box is 4x(6 - x)(4 - x)
Step-by-step explanation:
1. Since the squares of length x are cut from the corners of the cardboard, the height of the box is the length of a square which is x.
2. Since we have 8 inch by 12 inch, its length is 8 inches and its width 12 inches.
Since squares of x length are cut from the corners of the cardboard, the length of the box is 8 - 2x
3. Since we have 8 inch by 12 inch, its length is 8 inches and its width 12 inches.
Since squares of x length are cut from the corners of the cardboard, the width of the box is 12 - 2x
4. The volume of the box is V(x) = length × width × height = (12 - 2x)(8 - 2x)x = 2 × 2x(6 - x)(4 - x) = 4x(6 - x)(4 - x)
