Understanding the Problem

To find the volume of a right rectangular prism, we need to multiply the base area by the height. The base area is given as 2122 \frac{1}{2} square inches, and the height is given as 111211 \frac{1}{2} inches. We will first convert these mixed numbers to improper fractions to make the calculation easier.

Converting Mixed Numbers to Improper Fractions

To convert a mixed number to an improper fraction, we multiply the whole number part by the denominator and then add the numerator. The result is then written as the new numerator over the denominator.

  • 2122 \frac{1}{2} can be converted to an improper fraction as follows:
    • Whole number part: 2
    • Denominator: 2
    • Numerator: 1
    • Multiply whole number part and denominator: 2 x 2 = 4
    • Add numerator: 4 + 1 = 5
    • Result: 52\frac{5}{2}
  • 111211 \frac{1}{2} can be converted to an improper fraction as follows:
    • Whole number part: 11
    • Denominator: 2
    • Numerator: 1
    • Multiply whole number part and denominator: 11 x 2 = 22
    • Add numerator: 22 + 1 = 23
    • Result: 232\frac{23}{2}

Calculating the Volume

Now that we have the base area and height in improper fraction form, we can calculate the volume by multiplying them together.

Volume = base area x height = 52\frac{5}{2} x 232\frac{23}{2} = 5x232x2\frac{5 x 23}{2 x 2} = 1154\frac{115}{4}

Converting the Volume to a Mixed Number

To convert the improper fraction to a mixed number, we divide the numerator by the denominator and write the remainder as the new numerator.

1154\frac{115}{4} can be converted to a mixed number as follows:

  • Divide numerator by denominator: 115 ÷ 4 = 28 with a remainder of 3
  • Result: 283428 \frac{3}{4}

Conclusion

The volume of the right rectangular prism is 283428 \frac{3}{4} cubic inches.
