Answer 1

volume of match box =4×2.5×1.5=15cm cube


than
volume of 1 match box =15
so that volume of 144 match box=144×15=2160cm cube


volume of cartoon =1.5×84×60=7560
than

15 cm cube taken by 1 packet
so that 1 cm cube taken by 1÷15 packet
so that 7560 cm cube taken by 1÷15×7560=504 packets

Answer 2

volume of one matchbox= 4*2.5*1.5
= 15 cm^3
volume of packet containing 144 match boxes= 15*144
= 2160 cm^3
volume of cartoon= 1.5*84*60
=7560 cm^3
no. of packet in cartoon= 7560/2160
3 packets and half packet
