A ribbon is 3meteres long i need 8 pices of ribbon each 40cm long.how many centimeteres shorter is the ribbon than the length i need

Answer 1

Actual Length of ribbon = 3m = 300cm
Ribbon needed = 40×8 cm = 320 cm

therefore the ribbon is 320-300 cm short .
OR the ribbon is 20 cm short than needed

Answer 2

Answer:

Ribbon is 20 cm shorter than required

Step-by-step explanation:

Given,

Length of ribbon = 3m

1 m = 100 cm

So,

3m = 3 * 100 = 300 cm

Number of pieces required = 8

Length of each piece = 40 cm

So,

Total length of ribbon required= 40 * 8 = 320 cm

Difference between lengths = 320 - 300

= 20 cm

Since,

Length required is 320 cm and available length is 300 cm,

Hence,

Ribbon is 20 cm shorter than required
