Question

The lenght breadth and height of a cuboid is in ratio of 5:4:3 and Total surface area of it is 846cm² than find its length breath and height

Answer 1

Answer:

Step-by-step explanation:

let length=5x; breadth=4x; height=3x

TSA of cuboid=846

2(lb+bh+hl)=846

2(20x^2+12x^2+15x^2)=846

2(47x^2)=846

94x^2=846

x^2=9

x=3

Therefore,

Length=5x=15 cm

breadth=4x= 12 cm

height=3x= 9 cm
