Let the numbers be in terms of x.
Now we have 3x 4x and 5x
Acc. to the question:
3x X 4x X 5x = 480
 60x = 480
 x = 480 ÷ 60
 x^3 = 8
 x = 2 ( cube root of 8 is 2)
Now. 3x will be 3 times 2 》 3 x 2 = 6
Similarly, 4x = 4 x 2 = 8
and 5x = 5 x 2 = 10
Hence, the numbers are 6, 8 and 10.

Let the numbers be 3x , 4x and 5x
Product of numbers=480

3x×4x×5x=480

60x³=480

x³=480/60

x³=8

x=2

3x=3×2=6
4x=4×2=8
5x=5×2=10

Hence numbers are 6 , 8 and 10
