Question

hlooo guys help me ​

Answer 1

Answer:

let the length be- 3y

let the breadth be - 2y

let the height be- 1y

tsa(total surface area)=2(lb+bh+hl)

3168=2(3y*2y + 2y*1y + 1y*3y)

3168/2= 6y² + 2y² + 3y²

1584= 11y²

y^2= 1584/11= 144

y=root of 144

y= 12

length=3y=3*12= 36

breadth=2y=12*2= 24

height=y=12

hope it helps

have a good day
