Explanation
The formula for density is given as;
[tex]\text{density}=\text{ }\frac{mass}{volume}[/tex]Given the height as 26ft, width as 40ft and length as 36ft we can get the volume of the water that will fill the aquarium to be.
[tex]\text{Volume = 40 x 26 x 36=37440 cubic ft}[/tex]Since one gallon of water is approximately 0.134 cubic feet. Therefore, 37440 cubic feet becomes;
[tex]\frac{37440}{0.314}=279402.9851[/tex]The mass becomes the weight;
[tex]\begin{gathered} \text{weight}=\text{ density x volume} \\ \text{weight}=\text{ 8.33 x279402.9851} \\ \text{weight}=\text{ 2327426.9Ibs} \end{gathered}[/tex]Answer: First Option
