Question

Joan is filling a 2-liter soda bottle with different colors of sand to make an art project for her class. She has 1,000 milliliters of
red sand, 35 centiliters of blue sand, and 2,5 deciliters of yellow sand in the bottle, but it is not full yet. How many liters of
purple sand will she need to use to have the bottle completely full?

Answer 1

Answer:

0.4 l of purple sand

Step-by-step explanation:

Volume to be filled in:

• 2 liter = 2000 ml

Red sand

• 1000 ml

Blue sand

• 35 centiliters = 35*10 ml = 350 ml

Yellow sand

• 2.5 deciliters = 2.5*100 ml = 250 ml

Total volume filled:

• 1000 + 350 + 250 = 1600 ml

Purple sand needed:

• 2000 - 1600 = 400 ml = 0.4 l

Answer is 0.4 l of purple sand required
