Question

hello all here is my question,

The surface area of a cuboid is 3328m^2. Its dimensions are in the ratio 4:3:2 , then the volume of the cuboid is ?
I want full solution
The answer must be content quality and speed must be very fast.

Answer 1

Hey mate here is ur query...

________________

let the proportion ratio is x
hence length=4x
breadth=3x
height=2x

Now volume of cubiod=2(lb+bh+lh)=3328m²

or lb +bh +lh= 1664

or 4x*3x +3x*2x +4x*2x =1664

or 26 x² = 1664

or x² = 64

or x =±8

but take x=+8

& length=8*4=32
breadth=8*3=24
height=8*2=16

Hence volume= l*b*h

=32*24*16m³

=12288m³ required volume
