Question

The volume of a cuboid is 3600 cm and its height is 12 cm. If the length and breath are in the ratio 4:3,find its length and breath

Answer 1

v=3600cm³

h=12cm

the ratio of length and breadth=4:3

let their lenght be4x and breadth be 3x

now, we know that

v=l*b*h

3600=4x*3x*12

3600=144x²

x²=3600/144

x²=25

x=5cm

now length=4x=4*5=20cm

and breadth=3x=3*5=15cm

so length=20cm and breadth=15cm
