There are two aquariums in a science room. One of the aquariums is 18 inches wide, 25 inches long, and 12 inches high. If there are 231 cubic inches in a gallon, how many gallons of water can the aquarium hold (to the nearest tenth of a gallon)?

First, you have to find the volume of the aquarium. Since the aquarium is a rectangular prism, the formula for the volume is L x W x H.

L= 15, W=18, and H= 12.

15 x 18 = 270 270 x 12 = 3,240

Second, since there are 231 cubic inches in a gallon, we have to divide our 3,240 by 231.  

3,240 divided by 231 = 14.025974.

Now, we just round it down to 14 gallons.

The aquarium can hold 14 gallons of water.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
