Question

He length, breadth and height of a cuboid are in the ratio 19 : 11 : 13. if length is 30 cm more than height, then what is the volume (in cm3 ) of this cuboid

Answer 1

l = 19x
b = 11 x
h = 13 x

19x = 13x + 30
6x =30
x = 5

volume= l b h
v= 19×13×11×5×5×5 = 339625

Answer 2

L  :  B :  H  =  19 :  11  :  13

given that length is 30cm more than height,

L = H + 30  =  43 cm

volume of cuboid   =  L X B X H  =  19  *  11  * 43  = 8987 cm3
