Sample questions

1. What is the volume of a cuboid with dimensions 5 cm, 3 cm, and 2 cm?

   1. 30 cm³
   2. 10 cm³
   3. 15 cm³
   4. 20 cm³
   Show answer

   Answer: A. 30 cm³

   The volume of a cuboid is calculated as length × width × height. Therefore, 5 cm × 3 cm × 2 cm = 30 cm³.

2. If a cylinder has a diameter of 10 cm and a height of 3 cm, what is its volume?

   1. 235.5 cm³
   2. 282.6 cm³
   3. 300 cm³
   4. 450 cm³
   Show answer

   Answer: A. 235.5 cm³

   Diameter is 10 cm, so radius is 5 cm. Volume = πr²h = 3.14 × 5² × 3 = 235.5 cm³.

3. Find the volume of a cylinder with radius 6 cm and height 10 cm.

   1. 1130.4 cm³
   2. 1131.6 cm³
   3. 1134.8 cm³
   4. 1136 cm³
   Show answer

   Answer: B. 1131.6 cm³

   Volume = πr²h = 3.14 × 6² × 10 = 1131.6 cm³.

4. Find the volume of a cuboid with l = 10 cm, b = 5 cm, h = 4 cm.

   1. 200 cm³
   2. 150 cm³
   3. 210 cm³
   4. 220 cm³
   Show answer

   Answer: A. 200 cm³

   Volume of a cuboid is length × width × height. Therefore, 10 cm × 5 cm × 4 cm = 200 cm³.

5. What is the surface area of a cuboid with dimensions 7 cm, 4 cm, and 10 cm?

   1. 376 cm²
   2. 372 cm²
   3. 360 cm²
   4. 364 cm²
   Show answer

   Answer: A. 376 cm²

   Surface Area = 2(lw + lh + wh) = 2(7×4 + 4×10 + 7×10) = 376 cm².
