Answer 1

a. 8 m 8 cm

= 8 × 100 + 8 (1m = 100 cm)

= 800 + 8

= 808 cm

b. 3m

= 3 × 100

= 300 cm

c. 3,020 m

= 3020 × 100

= 3,02,000 cm

d. 10 m 12 cm

= 10 × 100 + 12

= 1000 + 12

= 1012 cm

e. 5 m 72 cm

= 5 × 100 + 72

= 500 + 72

= 572 cm

f. 30 m 228 cm

= 30 × 100 + 228

= 3000 + 228

= 3228 cm
