Answer 2

The dimensions of the cuboid are 0.5 m , 0.4 m and 0.3 m

Step-by-step explanation:

The Dimensions of closed cuboid are in the ratio 5:4:3

Let the ratio be x

Length of cuboid  = 5x

Breadth of cuboid = 4x

Height of cuboid = 3x

Total surface area of cuboid = $2(lb+bh+hl)=2(5x \times 4x + 4x \times 3x + 3x \times 5x)= 94x^2$

We are given that the total surface area is 0.94 square metre

So,$94x^2 = 0.94$

$x=\sqrt{\frac{0.94}{94}}$

x=0.1

Length of cuboid  = 5x =5(0.1)= 0.5 m

Breadth of cuboid = 4x =4(0.1)=0.4 m

Height of cuboid = 3x =3(0.1)=0.3 m

Hence  the dimensions of the cuboid are 0.5 m , 0.4 m and 0.3 m
