Answer:
The ribbon is 20 cm shorter that the required lenght
Step-by-step explanation:
1m = 100 cm
therefore
3 metres = 300 cm
8 pieces of ribbon 40cm are required
therefors
the required length = 40 multiplied by 8
therefore the required lenght of the ribbon
=320cm
the difference between the lenght of the ribbon needed and the actual lenght of the ribbion
= 320 - 300
= 20 cm
