Volume of 1st aquarium = 11 * 13 * 14 = 2002
volume of 2nd aquarium = 21 * 14 * 30 = 8820
if 5 minutes = 2002
1 minute = 2002\5 = 400.4
minutes to fill the 2nd aquarium is 8820/400.4 = 22.028(approximately)
For a box shown in the images, to see the more cost-effective option, one has to simply compare which of the two boxes has the large volume. This can be done by multiplying the length, width, and the height to find the volume. This is shown below:
Box A:
Volume = 2 * 3 * 4 = 24 ft^3
Box B:
Volume = 2 * 5 * 2.5 = 25 ft^3
Therefore, the second box is the more cost-effective of the two.
Answer:

Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Volume of cylindrical vase = 
As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,
Volume of cone =
× Volume of cylindrical vase
By putting the value, we get
Volume of cone =
× 63
Volume of cone = 
Answer: 44 degrees
