Question

The total surface area of acuboid is 13950cm cube and its length breadth and height are given in the ratio 2:3:5. find the lateral surface area

Answer 1

Answer:

let

the ratio be 2x,3xand4x

now

2l+2b+2h=13950

18x=13950

X=13950/18

X=775

length=775×2=1550

breadth=775×3=4650

height=775×4=18600
