Question

The diemensions of cuboidal
are in a ratio
1.2.3
and its
total surface area is 88m² find the
diemention
​

Answer 1

Let the length of the cuboid =x, breadth =2x, height =3x

Total surface area of a cuboid =2(l×b+b×h+l×h)

Given, total surface area of the cuboid =88m²

⇒2(x×2x+2x×3x+x×3x)=88m²

⇒22x²=88

⇒x=2

Hence, the length of the cuboid =x=2m, breadth =2x=4m, height =3x=6m

HOPE THIS WILL HELP YOU.
