Answer:
Volume of a rectangular prism = x^3 - 4x^2
Step-by-step explanation:
V = L*W*H
Where,
V= Volume of a rectangular prism
L= Length
W= Width
H= height
Volume of a rectangular prism= Length × Width × Height
Let
length of the box = x
width = length
Width = x
Height= x - 4
Volume of a rectangular prism= Length × Width × Height
= x * x * (x - 4)
= x^2 * (x - 4)
= x^3 - 4x^2
Volume of a rectangular prism = x^3 - 4x^2
