Question

Each side of a cube is decreased by 25%. Find the ratio of the volumes of the original cube and the resulting
cube​

Answer 1

Answer:

64:27 or 64 /27

Step-by-step explanation:

Let the side of cube = 10 cm

original volume = 10 *10* 10 = 1000 cm

Now , side of new cube : = 10 - 25% of 10 = 7.5

new volume = 7.5 *7.5 *7.5 = 421.875 cm

required ratio

1000/ 421.875

1000000/ 421875

64/ 27 or 64 : 27
