Answer:
No, she cannot fit it into the box
Explanation:
The way to know is this is simply find the total surface area of the cube. This helps to know the capacity of the cube.
From the question, the side length of the cube is 9 inches;
Mathematically, the area of a cube is 6l^2
Thus, the total surface area of the cube = 6 * 9 * 9 = 486 square inches
Seeing that what she is trying to fix is less than the total surface area, then we can say that she cannot fix 1,000 square-inch cubes inside the box
