We have been given that a vase has the shape of a rectangular prism. The inside of the vase is also a rectangular prism. We are asked to find the volume of the solid part of the vase .
The volume of solid part of the vase is equal to volume of rectangular vase minus volume of inside of the vase.
We know that volume of rectangular prism is length times width times height.
[tex]\text{Volume of the solid part of the vase}=25\cdot 8\cdot 10-22\cdot 5\cdot 4[/tex]
[tex]\text{Volume of the solid part of the vase}=2000-440[/tex]
[tex]\text{Volume of the solid part of the vase}=1560[/tex]
Therefore, the volume of the solid part of the vase is 1560 cubic cm.
