Math Problem Statement

Given the information in the diagram below, determine the height of the prism. Volume = 180x^3 - 150x^2 + 20x Area of Base = 18x^2 - 15x + 2 Height = ?

Solution

To determine the height of the prism, we use the formula for the volume of a prism:

Volume=Base Area×Height\text{Volume} = \text{Base Area} \times \text{Height}

Given:

Volume=180x3150x2+20x\text{Volume} = 180x^3 - 150x^2 + 20x Area of Base=18x215x+2\text{Area of Base} = 18x^2 - 15x + 2

We can find the height by rearranging the formula:

Height=VolumeArea of Base\text{Height} = \frac{\text{Volume}}{\text{Area of Base}}

This involves dividing 180x3150x2+20x180x^3 - 150x^2 + 20x by 18x215x+218x^2 - 15x + 2. Let’s perform this polynomial division:

  1. Divide the leading terms: 180x318x2=10x\frac{180x^3}{18x^2} = 10x.
  2. Multiply 10x10x by 18x215x+218x^2 - 15x + 2 and subtract from the original volume polynomial.
  3. Repeat the process with the new polynomial obtained after subtraction.
