Step-by-step explanation:
Answer:
1730 inches cubed
Step-by-step explanation:
We can add in the missing piece of the shape, then subtract it later. The aquariam is 18 by 10 at the base and has a height of 11 (5+6).
18•10•11=1980
Now we need to figure the volume of the empty space. The empty space has dimensions of 5, 10, and 5.
5•5•10=250
1980-250=1730
2+6x=4. i used x but you can use any variable
