Step-by-step explanation:
otal surface area is 504cm

The length, breadth, and height of a cuboid are in the ratio 6:5:3
total surface area =2(lb+bh+lh)
504 = 2(30x
2
+15x
2
+18x

)
504 = 2 x 63x

504 = 126x

x

=
126
504
= 4
∴x=2cm
Therefore,length= 6x=6x2 = 12cm
breadth = 5x =5(2) =10cm
height = 3x=3(2)=6cm
Volume of cuboid = area of the base x height = l×b×h = 12 x 10 x 6 = 720cm
