1.	The length breadth and height of a cuboid are in the ratio of 7 is to 6 is to 5 if the surface area of the cuboid is 1926 metre cube find the find its dimensions
Answer» Step-by-step EXPLANATION: Surface area of cuboid = 2(lb+bh+hl) LET the ratio be X Length = 7x Breadth = 6x Height = 5x = 2(7x6x+6x5x+5x7x) = 1926 = 2(42x+30x+35x) = 1926 = 2107x = 1926 = 214x = 1926 = x = 9 7x = 79 = 63 6x = 69 = 54 5x = 59 = 45 Hope it helps you* *Hope it helps youPlease MARK it as brainliest*

Answer»

Step-by-step EXPLANATION:

Surface area of cuboid = 2(lb+bh+hl)

LET the ratio be X

Length = 7x

Breadth = 6x

Height = 5x

= 2(7x*6x+6x*5x+5x*7x) = 1926

= 2(42x+30x+35x) = 1926

= 2*107x = 1926

= 214x = 1926

= x = 9

7x = 7*9 = 63

6x = 6*9 = 54

5x = 5*9 = 45
