CAASPP Measurement and Geometry 2 — Questions and Answers
Question 1: A rectangular pool is 15 meters long and 8 meters wide. What is the perimeter of the pool?
- 23 meters
- 46 meters (Correct answer)
- 120 meters
- 56 meters
Correct answer: 46 meters
Perimeter of a rectangle = 2(length + width) = 2(15 + 8) = 2(23) = 46 meters.
Question 2: Which unit would be most appropriate to measure the volume of water in a swimming pool?
- Milliliters
- Liters
- Cubic centimeters
- Kiloliters (Correct answer)
Correct answer: Kiloliters
Kiloliters (or thousands of liters) are the most practical unit for the large volume of water in a swimming pool.
Question 3: A triangle has a base of 10 cm and a height of 6 cm. What is its area?
- 60 cm²
- 16 cm²
- 30 cm² (Correct answer)
- 120 cm²
Correct answer: 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 4: Two angles in a triangle measure 45° and 65°. What is the measure of the third angle?
- 90°
- 70° (Correct answer)
- 110°
- 80°
Correct answer: 70°
The sum of angles in a triangle is 180°, so the third angle = 180° − 45° − 65° = 70°.
Question 5: A cube has a side length of 4 inches. What is the total surface area of the cube?
- 64 in²
- 96 in² (Correct answer)
- 16 in²
- 48 in²
Correct answer: 96 in²
A cube has 6 faces, each with area 4² = 16 in², so total surface area = 6 × 16 = 96 in².
Question 6: On a coordinate plane, point A is at (2, 3) and point B is at (2, −5). What is the distance between the two points?
- 2 units
- 8 units (Correct answer)
- 6 units
- 10 units
Correct answer: 8 units
Since both points share the same x-coordinate, distance = |3 − (−5)| = |8| = 8 units.
Question 7: A circle has a diameter of 14 cm. What is its circumference? (Use π ≈ 3.14)
- 43.96 cm (Correct answer)
- 87.92 cm
- 21.98 cm
- 153.86 cm
Correct answer: 43.96 cm
Circumference = π × diameter = 3.14 × 14 = 43.96 cm.
