The correct option is B 45,000 m3
We know that volume of a cuboid =l×b×h
where l, b and h are the length, breadth and height of the cuboid, respectively.
Given: Length, l = 5 km = 5000 m
Breadth, b = 6 m
Height, h = 1.5 m
⇒ Volume of cuboid = 5000 × 6 × 1.5
= 45,000 m3
∴ Volume of the cuboid is 45,000 m3
