What is the volume of the rectangular prism? . choices: (63yd^3) (7yd^3) (22.5yd^3) (189yd^3)

Answer: (7yd^3)
Step-by-step explanation:
Width= [tex]3*\frac{1}{3}[/tex]
Length= [tex]7*\frac{1}{3}[/tex]
Height= [tex]9*\frac{1}{3}[/tex]
Width= 1
Length= 2.33333333333...
Height= 3
1*2.33333333333*3= 6.99999999999
6.99999999999 is round up to 7
So that would be (7yd^3)
