Answer:
Step-by-step explanation:
let side of cube=x cm
volume=x³ cm³
again side=(x-3) cm
volume=(x-3)³ cm³
x³-(x-3)³=1385
(a³-b³)=(a-b)(a²+ab+b²)
(x-x+3){x²+x(x-3)+(x-3)²}=1385
3(x^2+x²-3x+x²-6x+9)=1385
3(3x²-9x+9)=1385
9x²-27x+27=1385
9x²-27x+27-1385=0
9x²-27x-1358=0

To determine the excess amount, subtract 32 from 85.33 which has a numerical value of 53.33 grams.
X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
Any number 1-26 should work. the expression would me x<$26.
