Question

the dimensions of a cuboid are in the ratio of 5:3:1 and its total surface area is 414 metre square find its dimensions
​

Answer 1

Answer:

let the sides be 3x , 5x and x

Step-by-step explanation:

T.S.A OF CUBOID →

2(LB+BH+HL) = 414

5x . 3x + 3x . x + x . 5x = 207

solve it and u will get the amswer

pls mark as brainlist if possible

Answer 2

Answer:

let the length breadth and height of the cuboid be 5x,3x,1x

so 2*(lb+bh+lh)=414

2*(5x*3x+3x*1x+1x*5x)

2*(15x^2+3x^2+5x^2)

2*(23x^2)

46x^2=414

x^2=9

x=√9

x=3

length is 15m

breadth is 9m

height is 3m
