A cubic block of wood with side lengths of 10 cm is cut into smaller cubes with side lengths of 1 cm. What is the ratio of the surface area of the larger block of wood to the combined surface area of the smaller blocks of wood? Express your answer as a common fraction.

the large cube has a surface area of \(6 * 10^2 = 600\), and the smaller cubes have a total area of \(6 * 1000 = 6000\).

 

so, the ratio is \(\frac{600}{6000}\) = \(\frac{1}{10}\)

 

 

hope this helped! please let me know if you are still confused smiley
