Step-by-step explanation:

Dimensions of the cardboard box

Length=3/2m= 3/2×100

Breadth=3/4m= 3/4×100

= 75cm

Height = 60cm

Volume of the cardboard box=L×B×H

=150cm×75cm×60cm

=675000cm³

For the books:

Length=20cm

Length=20cmBreadth=10cm

Length=20cmBreadth=10cmHeight=7.5cm

Volume of the book=L×B×H

=20cm×10cm×7.5cm
