Give me a word problem to match (12x2)+(4x3)

The expression
\(12x^2 + 4x^3\) represents the total volume of a rectangular prism sculpture. The term
\(12x^2\) accounts for the base volume, and
\(4x^3\) represents the added volume of an extra layer on top, providing a model for calculating the total volume.

Let's consider a word problem that can be modeled by the expression
\(12x^2 + 4x^3\). Imagine a rectangular prism with sides of length x and a rectangular base. The expression represents the total volume of the prism, where
\(12x^2\) corresponds to the volume of the rectangular base, and
\(4x^3\) represents the volume of an additional rectangular layer stacked on top.

Suppose you are building a sculpture using identical rectangular prisms. The base of each prism has an area of
\(12x^2\) square units, and each prism is x units tall. The sculptor decides to add an extra layer to the top of each prism, increasing the height by x units. The expression
\(4x^3\) represents the additional volume of the top layer for each prism. Therefore, the entire expression
\(12x^2 + 4x^3\) gives the total volume of one prism with the added layer, and you can use it to calculate the total volume for a given number of prisms.
