Answer:
General Sherman tree has the greatest volume.
The General Sherman tree has 5.9 x 10^3 ft^3 ft^3 more volume than the General Grant tree.
The General Sherman tree has more volume than the Washington tree.
Explanation:
The tree with the largest number (cubic feet) has the greatest volume.
Now of the three trees listed, the General Sherman tree has the greatest number. Therefore, the General Sherman tree has the greatest volume.
The difference between the volume of General Sherman and the General Grant is
[tex]\begin{gathered} 5.25\times10^4-4.66\times10^4=(5.25-4.66)\times10^4 \\ =0.59\times10^4=\boxed{5.9\times10^3\text{ ft}^3.} \end{gathered}[/tex]
The difference between the volume of General Sherman and Washington is
[tex]\begin{gathered} 5.25\times10^4-4.785\times10^4=(5.25-4.785)\times10^4 \\ =0.465\times10^4=\boxed{4.65\times10^4\text{ ft}^3.} \end{gathered}[/tex]
