TEKS 3.7E Worksheets — Grade 3 Determine liquid volume (capacity) or weight using

Paola is filling a large cooler with ice for a picnic at the Gulf Coast. The cooler can hold 12 quarts of liquid. If she adds 5 quarts of ice to the cooler, how many more quarts can she add before it is full?

1. 7 quarts ✓
2. 5 quarts
3. 8 quarts
4. 6 quarts

Why: To find out how many more quarts Paola can add, subtract the amount of ice already in the cooler from the total capacity. The cooler holds 12 quarts, and she has added 5 quarts of ice. So, 12 - 5 = 7. Therefore, she can add 7 more quarts before the cooler is full.

Lucia is making her famous Texas-style salsa for a family gathering. She needs 2 cups of tomatoes and 1/2 cup of onions. If she already has 1 cup of tomatoes at home, how many more cups of tomatoes does she need to buy?

1. 1 cup ✓
2. 2 cups
3. 1/2 cup
4. 3 cups

Why: To find out how many more cups of tomatoes Lucia needs, we subtract the amount she already has from the total needed. She needs 2 cups of tomatoes and has 1 cup: 2 cups - 1 cup = 1 cup. Therefore, Lucia needs to buy 1 more cup of tomatoes.

Maria is making lemonade for a school picnic in Austin, Texas. She needs to fill five pitchers with lemonade for her classmates. Each pitcher holds 2 liters of lemonade. How many liters of lemonade does Maria need in total?

1. 10 liters ✓
2. 7 liters
3. 12 liters
4. 5 liters

Why: To find the total amount of lemonade Maria needs, multiply the number of pitchers by the volume of each pitcher. Maria has 5 pitchers and each holds 2 liters, so the calculation is 5 × 2 = 10 liters. Therefore, Maria needs 10 liters of lemonade.

Kenji went to the State Fair of Texas and bought lemonade to share with his friends. If he bought 2 large cups of lemonade that each hold 16 ounces and 3 small cups that each hold 8 ounces, how many ounces of lemonade did Kenji buy in total?

1. 56 ounces ✓
2. 48 ounces
3. 32 ounces
4. 40 ounces

Why: To find the total amount of lemonade Kenji bought, first calculate the volume of the large cups. Each large cup holds 16 ounces, so 2 cups will hold 2 * 16 = 32 ounces. Next, calculate the volume of the small cups. Each small cup holds 8 ounces, so 3 cups will hold 3 * 8 = 24 ounces. Now add both amounts together: 32 ounces + 24 ounces = 56 ounces. Thus, the total is 56 ounces.

Olivia is helping her family at a cotton farm in Lubbock, Texas. They need to fill a large container with water to keep the cotton plants hydrated. If the container holds 4 gallons of water and they already put in 2 gallons, how many more gallons of water do they need to add?

1. 2 gallons ✓
2. 4 gallons
3. 6 gallons
4. 8 gallons

Why: To find out how many more gallons of water Olivia needs to add, we can subtract the amount of water already in the container from the total capacity of the container. The container holds 4 gallons, and they already added 2 gallons. So, 4 gallons - 2 gallons = 2 gallons. Therefore, Olivia needs to add 2 gallons more.

Maria is making breakfast tacos for her family in Austin. She needs 4 cups of beans and 3 cups of cheese. How many cups of ingredients does she need in total?

1. 7 cups ✓
2. 12 cups
3. 1 cup
4. 5 cups

Why: To find the total number of cups of ingredients, you add the cups of beans and cheese together: 4 cups of beans + 3 cups of cheese = 7 cups in total.

Camila is making lemonade for her family at their home in Austin. She needs 4 liters of water to make a big batch of lemonade. How many milliliters of water does she need?

1. 400 milliliters
2. 1,000 milliliters
3. 4,000 milliliters ✓
4. 40,000 milliliters

Why: To find out how many milliliters are in 4 liters, we need to remember that 1 liter is equal to 1,000 milliliters. So, we multiply 4 liters by 1,000 milliliters per liter: 4 × 1,000 = 4,000 milliliters. Therefore, Camila needs 4,000 milliliters of water.

Maya is helping her family at their garden in Texas. They have three watering cans. One can holds 2 liters, the second can holds 3 liters, and the third can holds 4 liters. What is the total volume of water that all three watering cans can hold when they are full?

1. 9 liters ✓
2. 7 liters
3. 6 liters
4. 8 liters

Why: To find the total volume of water that all three watering cans can hold, add the volumes of each can: 2 liters + 3 liters + 4 liters = 9 liters. Therefore, the correct answer is 9 liters.
