Question

the ratio of length breadth and height of the cuboid of the volume m³ is 5:4:3. Then what is the value of x

Answer 1

Step-by-step explanation:

Consider a given The given The length, breadth and height of a cuboid are in the ratio 5:4:2 and the total surface area is 1216cm

2

,

Let, the dimension of cuboid are l=5x,b=4x and h=2x

Now, the surface area of cuboid =2(5x×4x+4x×2x+2x×5x)=76x

2

Now,

76x

2

=1216

x

2

=16

x=4
