slega [8]

Answer:

Step-by-step explanation:

It is given that A rectangular prism has a length of 1\frac{1}{4}yards a width of 2\frac{1}{2} yards, and a height of 4 yards.

Now, the volume of the prism is given as:

V=Length{\times}width{\times}height

V=\frac{5}{4}{\times}\frac{5}{2}{\times}4

V=\frac{25}{2}

V=12\frac{1}{2}cubic yards

Therefore, the volume of the rectangular prism will be V=12\frac{1}{2}cubic yards.
