Question

The ratio of two numbers is 1:2. The sum of their cubes is 72. Find the numbers and their cubes. Also, find the least number by which to divide the sum of cubes to get a perfect cube​

Answer 1

Answer:

Step-by-step explanation:

Sum of ratio = 1 + 2 = 3

Sum of their cube = 72

x³ + (2x)³ = 72

x³ + 8x³ = 72

9x³ = 72

x³ = 72/9 = 8

x = 2

2 x 2 = 4

Number 1 = 2

Number 1 cube = 8

Number 2 = 4

Number 2 cube = 64
