Weight & Capacity — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A reasonable estimate for a loaf of bread is about 1 pound.
Bread loaves typically weigh around one pound, making pounds a reasonable estimate.
2. A reasonable capacity for a kitchen sink is about 5 gallons.
Kitchen sinks hold several gallons of water, so gallons are the right estimate.
3. A reasonable weight for an apple is about 5 ounces.
Apples are light, so their weight fits in ounces, not in pounds or kilograms.
4. A reasonable amount of milk in a glass is about 1 cup.
A glass of milk usually holds about a cup, which is a small everyday capacity.
5. A reasonable weight for a car is about 2000 pounds.
Cars weigh a few thousand pounds, so pounds are needed for such heavy estimates.
6. A reasonable capacity for a soup pot is about 2 quarts.
A family soup pot typically holds around 2 quarts of soup, a fair estimate.
7. A reasonable weight for a slice of bread is about 1 ounce.
A thin slice of bread is light, so just one ounce is a reasonable estimate.
8. A reasonable estimate for a bathtub is about 40 gallons.
Bathtubs hold tens of gallons of water, so gallons are the right large unit.
9. A reasonable weight for a small book is about 8 ounces.
A thin book weighs a few ounces, usually about half a pound or 8 ounces.
