review
use unit cubes to measure the space inside a three - dimensional figure.
this figure has three dimensions: length, width, and height.
the space inside a three - dimensional figure is called volume. you can fill a figure with unit cubes to determine its volume.

1. circle the figures that would be measured using unit cubes.

images: rectangular prism, circle, triangle, cube

1. put an x next to the situation that would be measured using unit cubes.

______ karly is measuring the distance she drove to school.
______ karly is measuring what can fit in her lunch box.

1. ______ matt is measuring how much tape a band box needs.

______ matt is measuring the space a mirror will take on the wall.

1. ______ gwen is measuring how much of the floor a rug covers.

______ gwen is measuring how much will fit in a storage unit.

1. describe how to find the volume of a rabbit cage.

Answer:

Question 1: Circle the figures that would be measured using unit cubes.

Unit cubes are used to measure the volume of three - dimensional (3D) figures. A rectangular prism (first figure) and a cube (fourth figure) are 3D figures. A circle (second figure) and a triangle (third figure) are two - dimensional (2D) figures and are measured for area, not volume with unit cubes. So we circle the first (rectangular prism) and the fourth (cube) figures.

Question 2: Put an X next to the situation that would be measured using unit cubes.

• Measuring the distance a drone can travel is measuring length (1D), not volume.
• Measuring what can fit in a lunch box is measuring the volume of the lunch box (the space inside), which can be measured using unit cubes. So we put an X next to "Karly is measuring what can fit in her lunch box."

Question 3: Put an X next to the situation that would be measured using unit cubes.

• Measuring how much tape a band - aid needs is measuring length (for the perimeter or length of the tape), not volume.
• Measuring the space a mirror will take on the wall is measuring the area (2D space) of the mirror, not volume. Wait, no, if we consider the thickness of the mirror, but usually, when we talk about the space a mirror takes on the wall, we mean the area. But maybe there is a mis - interpretation. Wait, the other option: "Matt is measuring the space a mirror will take on the wall" is area, "Matt is measuring how much tape a band - aid needs" is length. Wait, maybe the question has a typo, but according to the idea of volume (unit cubes measure volume), neither? Wait, no, maybe I made a mistake. Wait, the first option is about tape length (1D), the second is about the space (area, 2D) of the mirror on the wall. But if we have to choose, maybe the question is looking for volume - related. But maybe the intended answer is that neither, but that can't be. Wait, maybe I misread. Wait, "Matt is measuring how much tape a band - aid needs" is length, "Matt is measuring the space a mirror will take on the wall" is area. So maybe there is an error, but if we follow the options, maybe the second one is about area, but unit cubes are for volume. So perhaps the question is not well - formed, but if we have to choose, maybe no X? But that's unlikely. Wait, maybe the "space a mirror takes on the wall" is area, but unit cubes are for 3D. So maybe the answer is no X, but that's not possible. Wait, maybe I made a mistake. Let's re - check. Unit cubes measure volume (3D space). So the first situation is length (1D), the second is area (2D). So neither is measured with unit cubes. But the question says "put an X next to the situation that would be measured using unit cubes", so maybe there is a mistake in the question, but if we have to choose, maybe no X. But that's odd.

Question 4: Put an X next to the situation that would be measured using unit cubes.

• Measuring how much of the floor a rug covers is measuring the area (2D) of the rug.
• Measuring how much will fit in a storage unit is measuring the volume (3D space) of the storage unit, which can be measured using unit cubes. So we put an X next to "Gwen is measuring how much will fit in a storage unit."

Question 5: Describe how to find the volume of a rabbit cage.

The rabbit cage is a rectangular prism (assuming it's a box - like shape). To find its volume, we can use unit cubes by filling the cage with unit cubes (if possible) and counting the number of unit cubes. Or, using the formula for the volume of a rectangular prism, \(V = l\times w\times h\), where \(l\) is the length, \(w\) is the width, and \(h\) is the height of the cage. We measure the length, width, and height of the cage (in the same unit) and then multiply them together to get the volume.

Final Answers:

1. Circle the first (rectangular prism) and fourth (cube) figures.
2. X next to "Karly is measuring what can fit in her lunch box."
3. No X (or if there is a mis - understanding, re - check the question).
4. X next to "Gwen is measuring how much will fit in a storage unit."
5. To find the volume of a rabbit cage (a rectangular prism), we can either fill it with unit cubes and count the number of cubes, or measure its length (\(l\)), width (\(w\)), and height (\(h\)) and use the formula \(V=l\times w\times h\).
