Answer:
<h2>The rate is 15 minutes per meter.</h2>
Step-by-step explanation:
It takes 9 minutes to fill a depth of 
meters.
Filling meters take 9 minutes time.
Filling 3 meters of the aquarium takes 
= 45 minutes time (Multiplying by 5 both the numbers).
In order to<u> fill 1 meter of the aquarium it will take </u>
<u> minutes</u> (Dividing by 3 both the numerical values).
H = x, L = 1.5 x;
L + W + H = 6
x + 1.5 x + W = 6
W = 6 - 2.5 x
Dimensions of the camera in terms of x:
x, 1.5 x, 6 - 2.5 x.
V = L x W x H
V = x * 1.5 x * ( 6 - 2.5 x ) = 9 x² - 3.75 x³
V ` = 18 x - 11.25 x² ( V max is when V` = 0 )
18 x - 11.25 x² = 0
x ( 18 - 11.25 x ) = 0
11.25 x = 18
x = 18 : 11.25
x = 1.6
The dimensions are:
L = 2.4
W = 2.0
H = 1.6
