Question

The ratio of length breadth and height of cubiod is 6:5:4. Find the len6 of the cubiod if the total surface area is 1332sq.cm​

Answer 1

Answer:

let the length be 6x breadth be 5x and heighe be 4x

Step-by-step explanation:

TSA = 2( lb + bh + hl )

1332 = 2 ( 30x^2 + 20x^2 + 24x^2)

666 = 74x^2

x^2 = 666/74

x^ 2 = 9

x = 3

Therefore length = 24cm

Answer 2

Answer:

length of the cuboid is 6 x 9 = 54cm

Step-by-step explanation:

2(6x.5x + 5x.4x + 6x.4x)=1332

30x+20x+24x = 666

74x/74 = 666/74

x= 9 cm
