(from unit 3, lesson 4.)

1. name a unit of measurement that is about the same size as each object.

a. the distance of a doorknob from the floor is about 1
b. the thickness of a fingernail is about 1
c. the volume of a drop of honey is about 1
d. the weight or mass of a pineapple is about 1
e. the thickness of a picture book is about 1
f. the weight or mass of a buffalo is about 1
g. the volume of a flower vase is about 1
h. the weight or mass of 20 staples is about 1
i. the volume of a melon is about 1
j. the length of a piece of printer paper is about 1
(from unit 3, lesson 2.)

Explanation:

• a: A doorknob is typically around 1 meter above the floor. Meters are a common unit for measuring height or distance in larger - scale contexts.
• b: The thickness of a fingernail is very small, and centimeters are too large. Millimeters are a more appropriate unit for such a thin object.
• c: A drop of honey is a very small volume. Milliliters are a common unit for measuring small volumes of liquid.
• d: A pineapple has a certain mass. Kilograms are a common unit for measuring the mass of medium - sized objects.
• e: The thickness of a picture book is relatively small. Centimeters are a suitable unit for measuring the thickness of such an object.
• f: A buffalo is a large animal. Tons are a unit for measuring very large masses.
• g: A flower vase has a volume. Liters are a common unit for measuring the volume of containers.
• h: 20 staples have a small mass. Grams are a common unit for measuring the mass of small objects.
• i: A melon has a volume. Liters are a reasonable unit for measuring the volume of a melon - sized object.
• j: A piece of printer paper has a length. Decimeters are a unit that can be used for measuring the length of an object like printer paper.
