CAASPP Measurement and Geometry 2

Question 1

A rectangular pool is 15 meters long and 8 meters wide. What is the perimeter of the pool?

Accepted Answer

46 meters

Answer

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?

Accepted Answer

Kiloliters

Answer

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?

Accepted Answer

30 cm²

Answer

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?

Accepted Answer

70°

Answer

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?

Accepted Answer

96 in²

Answer

A cube has 6 faces, each with area 4² = 16 in², so total surface area = 6 × 16 = 96 in².
