Height of a cuboid is 4cm less than its breadth and length is 6cm more than its breadth. If length of cuboid is 20cm, then what will be the volume of cuboid?

Correct option is B

The height of the cuboid is 4 cm less than its breadth. Therefore, the height h is:
h=b−4
The length of the cuboid is 6 cm more than its breadth. Therefore, the length lll is:
l=b+6
We are given that the length l=20, so:
b+6=20
b=20−6=14cm
Since h=b−4
h=14−4=10 cm
The volume V of a cuboid is given by:
V=l×b×h
Substitute the values of l=20 cm, b=14 cm, and h=10 cm:
V=20×14×10=2800 $$cm^3$$​​
