Answer: 90
Explanation:
First, we need to calculate the volume of one cube of sugar:
V = s³, where s is the side length of the cube
V = 2³ = 8 cm³
To find the number of cubes that can fit in a box of 720 cm³, we need to divide the volume of the box by the volume of one cube:
720 cm³ ÷ 8 cm³/cube = 90 cubes
Therefore, 90 cubes of sugar can fit in a box with a volume of 720 cm³.
