The areas of three adjacent faces of a cuboid are 30 cm2, 20 cm2 and…

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
