  5. A student measures a bar of soap with a length of 8.0 cm, a width of 5.4 cm, and a height of 2.6 cm. The soap has a mass of 88.0 grams.
    1. __________ _____ What is the volume of the soap?
    2. __________ _____ What is the density of the soap?
  6. ____________________ A student measures the length of a piece of soap using a ruler. Is the measurement a primary or calculated measurement?
  7. ___________ _____ A bar of soap is found to have a density of 1.3 g/cm³. If the volume of the soap is 50 cm³, what is the mass of the soap?
  8. ___________ _____ A lead cube is found to have a density of 11.4 g/cm³. If the mass of the cube is 365 grams, what is the volume of the cube?

    4. __________ _____ Determine the velocity ѵ of ball D.
  10. __________ _____ Calculate the velocity ѵ of a ball that rolls 2500 centimeters in 12.5 seconds.
  11. __________ _____ Calculate the distance a ball with a velocity ѵ of 200 cm/s will roll in 9 seconds.
  12. __________ _____ Calculate the time for a ball with a velocity ѵ of 200 cm/s to roll 1600 centimeters.

Body mass index= mass in kg height in meters2
slope= ( y2 − y1 ) ( x2 − x1 )
Volume V = length l × width w × height h
mass m = density ρ × Volume V
ρ= m V
distance d = velocity ѵ × time t
ѵ= Δd Δt
