CAASPP Measurement and Geometry 3 — Questions and Answers
Question 1: What is the volume of a rectangular prism with length 5 cm, width 3 cm, and height 4 cm?
- 47 cm³
- 60 cm³ (Correct answer)
- 24 cm³
- 94 cm³
Correct answer: 60 cm³
Volume of a rectangular prism = length × width × height = 5 × 3 × 4 = 60 cm³.
Question 2: An angle measures 135°. How would this angle be classified?
- Acute
- Right
- Obtuse (Correct answer)
- Straight
Correct answer: Obtuse
An obtuse angle measures between 90° and 180°, so 135° is obtuse.
Question 3: A map uses a scale of 1 inch = 50 miles. If two cities are 3.5 inches apart on the map, what is the actual distance?
- 53.5 miles
- 175 miles (Correct answer)
- 143 miles
- 200 miles
Correct answer: 175 miles
Actual distance = 3.5 × 50 = 175 miles.
Question 4: Which of the following shapes has exactly one pair of parallel sides?
- Rectangle
- Rhombus
- Trapezoid (Correct answer)
- Square
Correct answer: Trapezoid
A trapezoid has exactly one pair of parallel sides, unlike rectangles, rhombuses, and squares which have two pairs.
Question 5: A student measures a pencil as 19 centimeters long. How long is this in millimeters?
- 1.9 mm
- 190 mm (Correct answer)
- 0.19 mm
- 1900 mm
Correct answer: 190 mm
1 centimeter = 10 millimeters, so 19 cm × 10 = 190 mm.
Question 6: A right triangle has legs measuring 6 cm and 8 cm. What is the length of the hypotenuse?
- 10 cm (Correct answer)
- 14 cm
- 100 cm
- 7 cm
Correct answer: 10 cm
Using the Pythagorean theorem: c² = 6² + 8² = 36 + 64 = 100, so c = 10 cm.
Question 7: A circle has an area of 78.5 cm². What is its radius? (Use π ≈ 3.14)
- 25 cm
- 5 cm (Correct answer)
- 10 cm
- 2.5 cm
Correct answer: 5 cm
Area = π × r², so 78.5 = 3.14 × r², r² = 25, r = 5 cm.
