Three no.s are in the ratio 1:2:3 the sum of their cube is 7776 find the numbers

6,12,18

Step-by-step explanation:

write the question as an equation

(1x)^3 + (2x)^3 + (3x)^3 = 7776

Simplify, rearrange and solve.

1x^3 +8x^3 + 27x^3 = 7776

36x^3 = 7776

x^3 = 216

x = 6.

Now, the numbers were= x, 2x, 3x = 6,12,18

Hope this helps

because it's a square, all of the sides are equal length so you can do

4(6x+3)

which equals 24x+12
