Question

The lenght , breadth and height of a rectangular solid are in the ratio of 6:5:4 . If it's total surface area is 5328 cm sq. Its height is equal to :
1. 36 cm
2.30 cm
3.24 cm
4. none of these ​

Answer 1

Answer:

let the lenght breadth and height be x

length = 6x

breadth= 5x

height = 4x

area is 5328cm²

6x+5x+4x= 5328

15x= 5328

x = 5328/15

x=355.2

lenght = 6*355.2 = 2131.2

breadth = 5*355.2 = 1776

height = 4*355.2 = 1420.8

so the height will be 1420.8 (none of these)
