Question

Volume of a cubiod is = l×b×h length is three times its breadth and heigh is height is half of its length find its column if breadth is Bcm

Answer 1

I think the answer is
$9 {b}^{3}$/2

Answer 2

we have breadth = B
therefore
l = 3B
and h = 3B/2
now
Volume = lbh = 3B × B × 3B/2 = 9B^3/2
