Answer: About 4 square bales.
Step-by-step explanation:
The formula for calculate the volume of a rectangular prism is:
[tex]V_r=lwh[/tex]
Where "l" is the lenght, "w" is the width and "h" is the height.
The volume of a cylinder can be found with this formula:
[tex]V_c=\pi r^2h[/tex]
Where "r" is the radius and "h" is the height.
Then, the volume of the traditional square bale which has the shape of a rectangular prism, is:
[tex]V_1=(2\ ft)(2\ ft)(4\ ft)\\\\V_1=16\ ft^3[/tex]
Since the radius of a circle is half the diameter, you can identify in the figure attached that the dimensions of a large round bale are:
[tex]r=\frac{4\ ft}{2}=2\ ft\\\\h=5\ ft[/tex]
Then its volume is:
[tex]V_2=\pi (2\ ft)^2(5\ ft)\\\\V_2=62.83\ ft^3[/tex]
Finally, dividing the volumes, you get the following result:
[tex]\frac{62.83\ ft^3}{16\ ft^3}\te\approx4[/tex]
Therefore, you can conclude that about 4 square bales contain the same amount of hay as one large round bale.
