Hi!
For this question, you want to find the volume of each aquarium. To find volume, just multiply all the dimensions dogether.
For the small aquarium: 3 * 1.5 * 2 = 9 feet cubed
For the large aquarium: 6 * 3 * 4 = 72 feet cubed
Therefore, no, he is not correct, as the large aquarium holds 8 times as much water as the small one. Option D is correct.
If you would like a faster way to do this, if you look at the two dimensions, you'll see each dimension for the large aquarium is two times the respective dimensions of the small one. Since there are three dimensions, and each is two times larger, you can just do 2 * 2 * 2 to get 8 times, as the dimensions are all multiplied with one another.
Hope this helped!
Answer:
The answer is
Step-by-step explanation:
Remember:
First: Find the slope.
.
Second: Solve for the y-intercept
.
Third: Plug in.
The volume of a rectangular prism is represented by the following equation:
where w is the width , l is the length, and h is the height
Replace 
with 
since the length is tripled
From this, we see that this new volume is 3x larger than the original. Thus, the volume is tripled when its length is tripled.
Let me know if you need any clarifications, thanks!
