Answer:
The volume of the ornament is 
Step-by-step explanation:
we know that
The volume of the ornament is equal to the sum of the volume of the two congruent square pyramids
so
![V=2[\frac{1}{3}b^{2} h]](https://tex.z-dn.net/?f=V%3D2%5B%5Cfrac%7B1%7D%7B3%7Db%5E%7B2%7D%20h%5D)
we have


substitute
![V=2[\frac{1}{3}(2)^{2} (2.5)]](https://tex.z-dn.net/?f=V%3D2%5B%5Cfrac%7B1%7D%7B3%7D%282%29%5E%7B2%7D%20%282.5%29%5D)

Convert to mixed number

The third and last option. To solve the equation we take the reciprocal of 3/4 because you cannot divide fractions so it would be 15• 4/3, but flip this it could also be 15 divided by 3/4 you would just need to further simply the expression
