Answer:
Hence, the area of the largest cube is equal to 96 cm^2.
Step-by-step explanation:
Our aim is to find the value that represents the total surface area of the larger cube.
Since its volume is equal to 8 cm^3, we can easily conclude that each side, s, is equal to 8^(1/3) = 2.
Hence the area of each cube is equal to the areas of each face multiplied by 6, which is the number of sides of the cube.
Lets consider a to be the side of small cube.
The area of the larger cube is equal to 2a x 2a, which is the area of each face of the largest cube.
And it needs to be multiplied by 6. Then we get:
2 x 2 x 2 x 2 x 6 = 96
Hence, the area of the largest cube is equal to 96 cm^2.
