multiplying metrics

posted by .

im in 6th grade--we have a math problem to multiply 3km x 200m x5 can you walk me thorough how to get the answer? Thanks

  • multiplying metrics -

    already answered, but once more:
    3km x 200m x5
    = 3km x .2km x 5
    = 3 (km)^2

    or

    3km x 200m x5
    = 3000m x 200m x 5
    = 3000000 m^2
    but 1000000 m^2 = 1 (km)^2
    so we have 3 (km)^2
