Respuesta :
The volume of the box is 3x²- 36x + 108, where, x is the side length of the original piece of cardboard.
What is volume?
Volume is the amount of space taken up by an object. It is measured in cubic units.
According to the given problem,
Length of the side of the original piece of cardboard = x
We know, the the height of the box will be 3",
The dimensions of base will be (x-6) by (x-6)
The volume equation:
V = Length × width × height
= (x-6) * (x-6) × 3
= [(x-6)²] × 3
= 3( x² - 12x + 36)
= 3x² - 36x + 108
Hence, we can conclude that the volume (V) of the box is 3x² - 36x + 108.
