Surface area is what it seems to be. All of the area of the solid's faces together. Like a cube, just find the areas of all of the squares that make the cube then add them together.
1/9 of the aquarium was filled with 1/7 liter
1 whole fraction of the aquarium will be filled = 1/7 ÷ 1/9
= 1/7 * 9/1 = 9/7
9/7 liters or 1 2/7 liters will be needed.
Answer:
512cm^2
Step-by-step explanation:
Let's imagine cutting the square down that diagonal. Now, we have two isosceles right triangles with a hypotenuse with length 32cm. Let's take one of those triangles for now and focus on it. Let's give the one of the legs of a triangle some length x. Since both legs are the same length, by the Pythagorean theorem:

Since this leg makes up one side of the square, we can use it to calculate the area of the square, which is just the side length squared:

Answer:
5 feet high
Step-by-step explanation:
A= LxW
Yx4= 20
/4 /4
Y= 5ft
It is 5ft high
