If The Length, Breadth And The Height Of A Cuboid Are In The Ratio 6: 5: 4 And If The Total Surface Area Is 33300 Cm2, Then Length Breadth And Height In Cms, Are Respectively?

Answer»

Length = 6X

Breadth = 5x 

Height = 4x in CM 

Therefore, 2(6x × 5x + 5x × 4x + 6x × 4x) = 33300 

148x2 = 33300 

=> x2 = 33300/148 = 225 

=> X = 15. 

Therefore, Length = 90cm, 

Breadth = 75CM

Height = 60CM 

90, 75 , 60 cm.

Length = 6x

Breadth = 5x 

Height = 4x in cm 

Therefore, 2(6x × 5x + 5x × 4x + 6x × 4x) = 33300 

148x2 = 33300 

=> x2 = 33300/148 = 225 

=> x = 15. 

Therefore, Length = 90cm, 

Breadth = 75cm, 

Height = 60cm 

90, 75 , 60 cm.
