Question

If the length, breadth and height of a cuboid are in the ratio 5 : 3 : 2 and its total surface area is 1216 cm square, then its length is :​

Answer 1

Step-by-step explanation:

let the coefficient of sides be x, then l:b:h=5x:3x:2x eq-i)

TSA of cuboid = 2(lb+bh+lh)=1216 eq-ii)

by putting eq-i) in eqii)
