The equation that can be used to find the length of the tank is 240 = l × 12 × 10
<h3>How to find the volume of rectangular prism?</h3>
The volume of a rectangular prism can be found as follows:
volume of rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
volume of rectangular prism = lwh
volume of rectangular prism = 240 ft³
h = 12 ft
w = 10 ft
Therefore, the let's find the length of the tank.
240 = l × 12 × 10
240 = 120l
divide both sides by 120
l = 240 / 120
l = 2

The goal is to find the radius of a circle which also helps to get the diameter. Finding the center helps to measure and know the circumference.
When we use arcsine, we are finding the angle while giving the trigonometric ratio.
Arcsin(u) = theta can be rewritten as:
sin(theta) = u
Sine is opposite over hypotenuse, so u/1 means that the side opposite to theta (the y value) is u, and the hypotenuse is 1.
We can use Pythagorean Theorem to find the adjacent (x value).
1^2 - u^2 = x^2
x = sqrt(1-u^2)
Back to the original question, we are trying to find cos(arcsin(u)). We just solved all the sides for our triangle using arcsin(u). Now we need to do cos(u).
Cosine is adjacent over hypotenuse.
So our answer is sqrt(1-u^2)/1
Or just sqrt(1-u^2)
3 x(4+4)= (3x4)+(3x4)
I am not completely sure, but I hope I helped!! (:
