Answer:

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: A = \frac{h*w}{2}

Pytagoras theorem: h^{2} + w^{2} = t^{2}

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

h^{2} + w^{2} = t^{2}

w^{2} = t^{2} - h^{2}

w = \sqrt{t^{2} - h^{2}}

So the area is:

A = \frac{h*w}{2}

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}

A rectangular aquarium 3 ft. x 2 ft. 1 ft. is 2/3 full of water. In cubic feet, how much water is in the tank
tatuchka [14]

To find the volume of a rectangular prism, we must multiply the length * width * height.


In this case,


Volume = 3 ft * 2 ft * 1 ft

= 6 ft^3


Because this tank is 2/3 full with water, to find out how much water is in the tank, we must multiply 2/3 by the total volume of the tank (6 ft^3).


2/3 * 6 ft^3 = 4 ft^3


This means that there are 4 cubic feet of water in the tank.


Hope this helps!
