Question

the dimension cuboid ate in the ratio 5:3:1 and T S A is 414msquare. find the dimension​

Answer 1

Answer:

Ratio of dimensions=5:3:1

Let length,breadth and height be 5x,3x and x m respectively.

TSA of cuboid=414sq.m

    2(lb+bh+hl)=414

(5x*3x)+(3x*x)+(x*5x)=414/2

15x^2 + 3x^2 + 5x^2=207

       23x^2=207

           x^2=9

             x=√9

             x=3

Length    =5x=5*3=15m

Breadth  =3x=3*3=9m

Height    =x =3m
