<em>Greetings from Brasil....</em>

Let's solve this 2nd degree equation.

6b² + 8b - 10 = 0       dividing all terms by 2

3b² + 4b - 5 = 0         applying the baskara formula

Δ = 4² - 4 · 3 · (- 5)

Δ = 76

b = (- 4 ± √76)/6      so

<h2>b' = (- 4 + √76)/6</h2><h2>b'' = (- 4 - √76)/6</h2>

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

  • Height: 11
  • Base Dimensions: 4.3 and 3.2

Area of Base:

  • 4.3 * 3.2
  • 13.76  

Next, we multiply 13.76 by 11.

  • 13.76 × 11
  • 151.36

Lastly, divide by 3 and round to nearest tenth.

  • 151.36 ÷ 3  
  • 50.453333..
  • ≈ 50.5

Therefore, the answer is 50.5 m^3
