Question

The length, breadth and height
of in cuboid are in the outis ist
4: 3:2 cand its total surface wees
in 5200 cm. Find the dimension
of cuboid,​

Answer 1

Let the length = 4x

breadth = 3x

height = 2x

volume = length*breadth*height

5200 = 4x*3x*2x

5200 = 24x³

5200/24 = x³

Answer 2

Answer:

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

let the dimension be x

5200=2(4x*3x+3x*2x+2x*4x)

5200=2(12x^2+6x^2+8x^2)

5200=2(26x^2)

5200=52x^2

5200/52=x^2

100=x^2

x=10

first dimension = 4*10=40cm

second dimension = 4*3=12cm

third dimension = 4*2 = 8cm
