Question

the ratio of the length breadth and height of a cuboid is 5 ratio 3 ratio 2 if total surface area of cuboid is 558 CM square then find their edges​

Answer 1

Step-by-step explanation:

let ratio = x

5=5x

3=3x

2=2x

5x +2x +3x = 558

10x =558

x =558/10

x =55.8

length = 5x 55.8

=279cm

breadth=3x 55.8

=167.4cm

height = 2x 55.8

=111.6 cm

Answer 2

Step-by-step explanation:

let the length,breadth,heght be 5x,3x,2x........ (1) respectively

we know......

surface area of cuboid=2 (lb+bh+hl)

558=2 (lb+bh+hl)

.......

.........

.....

solve and get the value of x

and then substitute in place of x in equation (1)

finally you will get the answer.
