Question

the length breadth and hight of a cuboid are in the ratio 4:3:2. if its total surface area is 468sq.cm find its dimensions​

Answer 1

Answer:

l=12,b=9,h=6

Step-by-step explanation:

let l=4@,b=3@,h=2@

TSA =468

2(4@×3@+4@×2@+3@×2@)=468

12@×@+8@×@+6@×@=234

26@×@=234

@×@=9

@=3

therefore l=12,b=9,h=6

Answer 2

Answer:

4x*3x*2x=468

24x=468

x=468/24

x = 19.5

therefore.,

length = 4*19.5=78cm

breadth = 3*19.5=58.5cm

height= 2*19.5=39cm

hope it will help u..
