The areas of three adjacent faces of a cuboid are 30 cm², 20 cm² and 24 cm². The volume of the cuboid is:

120 cm³

Let the length , breath and height of the cuboid = l, b and h

And we know the area of a rectangle = length $\times$ breath

According to the question,

lb = 30

 bh = 20

 lh = 24

(lbh)² = 30 × 20 × 24

so the volume of cuboid = lbh = 120 cm
