Answer 1

Volume of the right rectangular prism is $112\frac{1}{2} \ \text{cm}^3$.

Solution:

Length of the prism = 5 cm

Width of the prism = $4\frac{1}{2}$ cm

Height of the prism = 5 cm

Volume of the prism = length × width × height

                                  $=5\times4\frac{1}{2}\times5$

To change improper fraction into mixed fraction.

                                 $=5\times\frac{9}{2}\times5$

                                  $=\frac{225}{2}$

To change mixed fraction into improper fraction.

                                 $=112\frac{1}{2}$

Volume of the right rectangular prism is $112\frac{1}{2} \ \text{cm}^3$.
