I've answered three of your questions. Now it's your turn. I'll be glad to check your answer.
To calculate the amount of glass needed to make a fish tank, you need to consider the dimensions of the tank and account for the fact that the tank is open on top.
The glass needed will depend on the sides and the bottom of the tank. Since the tank is open on top, it does not require any glass for the top.
To calculate the amount of glass needed for the sides, multiply the height of the tank by the perimeter of the base. For a rectangular tank, the perimeter is calculated by adding the length and width and then multiplying the sum by 2.
Perimeter = (Length + Width) * 2
In this case, the length is 12 inches and the width is 8 inches, so the perimeter is:
Perimeter = (12 + 8) * 2 = 40 inches
Next, multiply the perimeter by the height of the tank to get the total area of the sides:
Area of the Sides = Perimeter * Height
Area of the Sides = 40 * 9 = 360 square inches
To calculate the amount of glass needed for the bottom of the tank, multiply the length and width:
Area of the Bottom = Length * Width
Area of the Bottom = 12 * 8 = 96 square inches
Finally, add the area of the sides to the area of the bottom:
Total Glass Needed = Area of the Sides + Area of the Bottom
Total Glass Needed = 360 + 96 = 456 square inches
Therefore, you would need 456 square inches of glass to make a fish tank that is 12 inches long, 8 inches wide, and 9 inches high, with an open top.
