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
Since we are looking for the distance around the edges of the bedroom, we are actually finding the perimeter.
2L + 2W = perimeter where L is length and W is width. Plugging our known information into the equation:
2(13) + 2(12)
= 26 + 24
= 50
Your answer should be 50 feet. Hope this helps!
