Sample questions

1. What is the volume of a cube with side length 2 cm?

   1. 4 cm³
   2. 8 cm³
   3. 6 cm³
   4. 2 cm³
   Show answer

   Answer: B. 8 cm³

   The volume of a cube is calculated using the formula V = side³. For a cube with side length 2 cm, the volume is 2³ = 8 cm³.

2. If the dimensions of a box are doubled, how does the volume change?

   1. It doubles
   2. It triples
   3. It quadruples
   4. It remains the same
   Show answer

   Answer: C. It quadruples

   If the dimensions of a box (length, width, and height) are doubled, the new volume becomes 2L × 2W × 2H = 8LWH, which is four times the original volume.

3. A cone has a radius of 3 cm and a height of 4 cm. What is its volume? (Use π ≈ 3.14)

   1. 28.26 cm³
   2. 37.68 cm³
   3. 12.56 cm³
   4. 25.12 cm³
   Show answer

   Answer: B. 37.68 cm³

   The volume of a cone is V = (1/3)πr²h. For this cone, V = (1/3) × 3.14 × (3)² × 4 = 37.68 cm³.

4. A cylinder has a height of 10 cm and a base diameter of 8 cm. Calculate its volume. (Use π ≈ 3.14)

   1. 200.96 cm³
   2. 150.80 cm³
   3. 160.80 cm³
   4. 180.96 cm³
   Show answer

   Answer: A. 200.96 cm³

   Volume of a cylinder is V = πr²h. The radius is 4 cm. Therefore, V = 3.14 × (4)² × 10 = 200.96 cm³.

5. If a pool is filled to a depth of 2 m, with a length of 8 m and a width of 5 m, what is the volume of water in cubic meters?

   1. 80 m³
   2. 100 m³
   3. 10 m³
   4. 50 m³
   Show answer

   Answer: A. 80 m³

   Volume = length × width × height. Therefore, the pool can hold 8 m × 5 m × 2 m = 80 m³ of water.
