Spring Math & Reading — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The volume of a rectangular planter box is found by multiplying length times width times height.
Volume measures 3D space, so you need all three dimensions: length x width x height.
2. Volume is measured in cubic units, such as cubic inches or cubic centimeters.
Because volume measures three-dimensional space, it uses cubic units that account for length, width, and height.
3. On a coordinate grid, the point where the x-axis and y-axis meet is called the origin.
The origin is the starting point of a coordinate grid, located at (0, 0) where the x-axis and y-axis cross.
4. A garden planter that is 10 inches long, 5 inches wide, and 4 inches tall has a volume of 200 cubic inches.
Volume equals length x width x height, so 10 x 5 x 4 = 200 cubic inches.
5. The first number in an ordered pair tells how far to move along the x axis.
In an ordered pair like (3, 5), the first number tells how far to move horizontally along the x-axis from the origin.
6. A table that organizes data into rows and columns is often called a data table.
A data table uses rows and columns to organize information so it is easy to read, compare, and analyze.
7. If a raised bed holds 300 cubic inches of soil and each bag contains 100 cubic inches, you need 3 bags.
Dividing the total volume by the bag size gives 300 / 100 = 3 bags needed to fill the raised bed.
8. The second number in the ordered pair (3, 7) tells you to move 7 units up from the x-axis.
In the ordered pair (3, 7), the second number is the y-coordinate, which means you move 7 units up from the x-axis.
9. When two rectangular planters are stacked, the combined volume equals the sum of their individual volumes.
Stacking two planters combines their space, so you add their individual volumes together to find the total volume.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Volume of a box 6 in. x 4 in. x 3 in.
→ 72 cubic inches
28 feet
Ordered pair for 5 right and 2 up
→ (5, 2)
(5, 2)
The y-value in the point (8, 6)
→ 6
72 cubic inches
Perimeter of a 10 ft by 4 ft garden
→ 28 feet
6
Correct matches: Volume of a box 6 in. x 4 in. x 3 in. → 72 cubic inches; Ordered pair for 5 right and 2 up → (5, 2); The y-value in the point (8, 6) → 6; Perimeter of a 10 ft by 4 ft garden → 28 feet.
