Question

the length and breadth of a cuboid are in the ratio 4:5.the height and total surface area of the cuboid are 18cm and 3384cm square respectively.find its length and breadth.​

Answer 1

Answer:

here ,

height ,h =18 cm

length/breadth = 4/5

length =4k and breadth =5k

total surface area of the cuboid = 2(lb+bh+hl)

solving it we will find the value of

k=6 or -14.1(imp)

therefore,

length=4*6=24cm

breadth=5*6=30cm
