Question

The volume of a cuboid is 6400cm 3 .The length is 32cm.Its breadth and the height are in the ratio 2:1.Find breadth and height of the cuboid.

Answer 1

l=32 cm
ratio of breadth and height =2:1
b:h =2:1
let b=2x cm
h== x cm
volume of cuboid = 6400cm^3
lbh =6400
32*2x*x=6400
64*x^2=6400
x^2=6400/64
x^2=100
x=10
therefore
b=2x=2*10=20 cm
h=x =10 cm
