Question

the dimension of a cubiod are in the ratio 3:2:1 and total surface are is 162 sq.cm. find the length of the cubiod​

Answer 1

Answer:

x=3 Therefore length is 3x3=9 breath is 2x3=6 and height is 1x3=3

Step-by-step explanation:

let the ratio be 3x:2x:1x

then, TSA = length x breath x height = 3x x 2x x 1x= 6x cube

6x cube = 162

x cube = 162/6= 27

therefore x = 3
