Final answer:
To find the mass of each cube, divide the total mass of the box by the number of cubes. The mass of each cube in Box A is 33.21 grams, while the mass of each cube in Box B is 90 grams.
Step-by-step explanation:
To determine the mass of each cube, we need to divide the total mass of the box by the number of cubes.
Mass of each cube in Box A = Total mass of Box A / Number of cubes in Box A = 1760 grams / 53 cubes = 33.21 grams per cube.
Mass of each cube in Box B = Total mass of Box B / Number of cubes in Box B = 1620 grams / 18 cubes = 90 grams per cube.
