| What is the area of a general quadrilateral if the two triangles formed by its diagonal have areas of 15 cm² and 25 cm²? | Card: 19 / 30 |
| The area of the quadrilateral is the sum of the areas of the two triangles: 15 cm² + 25 cm² = 40 cm². | Card: 20 / 30 |
| The volume of a cube with side length 2 cm is ___ cm³. | Card: 21 / 30 |
| Volume = s³ = 2³ = 8 cm³. | Card: 22 / 30 |
| True or False: The perimeter of a circle is referred to as its diameter. | Card: 23 / 30 |
| False. The perimeter of a circle is referred to as its circumference. | Card: 24 / 30 |
| If the radius of a sphere is 3 cm, what is its volume? | Card: 25 / 30 |
| Volume = (4/3)πr³ = (4/3)π(3)³ = 36π cm³. | Card: 26 / 30 |
| Calculate the surface area of a cuboid with dimensions 2 cm × 3 cm × 4 cm. | Card: 27 / 30 |
| Surface area = 2(lb + bh + lh) = 2(2×3 + 3×4 + 2×4) = 2(6 + 12 + 8) = 2(26) = 52 cm². | Card: 28 / 30 |
