Answer 1

Answer:

Area of 1 cake = l × b × h

= 9 × 5 × 2

= 90 cm square

= 0.009 metre square

Area of 1 box = l × b × h

= 1.5 × 0.9 × 0.5

= 0.675 metre square

No. of cakes that can be placed in the box =

Area of box/ Area of 1 cake

= 0.675/0.009

= 75 cakes

Answer 2

1m=100cm

so...

1.5m= 1.5×100 = 150cm

0.9m=0.9×100= 90cm

0.5=0.5×100=50cm

Volume of cuboid box

=150cm × 90cm × 50cm

= 675000cm³

Volume of soap cakes

=9cm × 5cm × 2cm

=90cm³

No. of cakes which can be placed

=675000cm³ ÷ 90cm³

=7500

FINAL ANSWER

=7500
