125 - 5x² = 0 when x = 5 sin θ
⇒ 125 - 5(5 sinθ)²
⇒ 125 - 5(25 sin²θ)
⇒ 125 - 125 sin²θ
⇒ 125(1 - sin²θ)
⇒ 125(1 - sinθ)(1 + sinθ) <em>This is simplified</em>
<em>Solving for θ:</em>
⇒ (1 - sinθ)(1 + sinθ) = 0
⇒ (1 - sinθ) = 0 (1 + sinθ) = 0
⇒ sinθ = 0 sinθ = -1
θ = 0° θ = 180°
Since neither value satisifies 0° < θ < 90° there is no solution

Well the formula for Volume of a Rectangular Prism is {Length x Width x Height = Volume}
So we know 18.5 x 9 x Length = 2,830.5
Divide by 18.5 and 9 and you are left with the length of 17 xD
I believe it will be 36 Im sorry if im wrong.
