Answer 1

Answer:

a) A stack of 100 coins would be in 32 centimetres

b) A stack of 1000 coins would be in 320 centimetres

Step-by-step explanation:

10 coins = 32mm

100 coins = 32×10 = 320m

1mm = 0.1cm

320mm = 32 cm

a) A stack of 100 coins would be in 32 centimetres

10 coins = 32mm

1000 coins = 32×100= 3200mm

1mm = 0.1cm

3200mm = 320 cm

b) A stack of 1000 coins would be in 320 centimetres
