A large rectangular shaped aquarium has a volume of 300 ft3. If the aquarium has a height of 3 feet and a length of four more feet than the width, find the length and width of the aquarium.​

length is 14.4ft and the width is 12.4ft

Step-by-step explanation:

Volume of the aquarium = length * width * height

Given

Volume = 300ft^3

Height = 3feet

l = w+4

Substitute

300 = 3w(w+4)

100 = w(w+4)

100 = w^2+4w

w^2+4w-100 = 0

w = 4±√16+400/2

w =4±√416/2

w = 4±20.4/2

w = 24.4/2

w = 12.2feet

Since l = w+4

l = 12.2+4

l = 16.4ft

hence the length is 14.4ft and the width is 12.4ft

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
