(b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Answer:

Part a) The total volume is [tex]98\ ft^{3}[/tex]

Part b) [tex]84\ ft^{3}[/tex]

Step-by-step explanation:

Part a)

Find the total volume

we know that

The volume of a rectangular prism is equal to

[tex]V=LWH[/tex]

we have

[tex]L=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft[/tex]

[tex]W=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft[/tex]

[tex]H=8\ ft[/tex]

substitute in the formula

[tex]V=(\frac{7}{2})(\frac{7}{2})(8)=98\ ft^{3}[/tex]

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Multiply the total volume by 6/7

so

[tex]98(6/7)=84\ ft^{3}[/tex]
