Answer:
21
Step-by-step explanation:
Volume of Rectangular Prism: LWH: Length * Width * Height
Volume of Rectangular Prism: [tex](1\frac{1}{2}) *(4)*(3\frac{1}{2})[/tex]
=> You can convert mixed fractions into improper fractions by the following steps so it's easier to solve the equation:
=> [tex]1\frac{1}{2}[/tex] would be [tex]\frac{3}{2}[/tex] as an improper fraction; [tex]3\frac{1}{2}[/tex] would be [tex]\frac{7}{2}[/tex] as an improper fraction. Whereas 4 would remain the same since it's a whole number.
=> Now, multiple everything together: ([tex]\frac{3}{2}[/tex]) * (4) * ([tex]\frac{7}{2}[/tex])
The answer would be 21!
Hope this helps!
