Question

1 a.) 20cm^2 to mm^2

b.) 50cm^3 to mm^3
c.) 3.75ha to cm^2
d.) 6.93litres to cm^3
e.) 6500mm^2 to cm^2
f.) 72km/hr to m/sec

Answer 1

a) 200 mm^2

b) 500 mm^2

c) 3.75e + 8

d) 6390 cm^2

e) 650 cm^2

f) 20 m/s

Explanation:

For a) and b): 1 cm = 10 mm, multiply 20 (and 50) by 10

For c): the formula is to multiply 1e + 8

For d): 1 Liter = 1000 Cubic Centimeters (hopefully that's what you're referring to)

For e): 10 mm = 1 cm, divide by 10
