A cube has six square faces, each of area 25 cm².
Thus, total area is 6 × 25 = 150 cm².
Choose an option to check your answer.
Cuboid volume is length × width × height.
Thus, 8 × 5 × 3 = 120 cm³.
Choose an option to check your answer.
Cylinder volume is πr²h.
Thus, π × 9 × 10 = 90π cm³.
Choose an option to check your answer.
Curved surface area is 2πrh.
Thus, 2π × 4 × 7 = 56π cm².
Choose an option to check your answer.
Rectangle perimeter is 2(length + width).
Thus, 2(8 + 5) = 26 cm.
Choose an option to check your answer.
Cone volume is one-third πr²h.
Thus, 1/3 × π × 9 × 12 = 36π cm³.
Choose an option to check your answer.
Rectangle area is length multiplied by width.
Thus, 12 × 7 = 84 m².
Choose an option to check your answer.
Sphere volume is 4/3 πr³.
Thus, 4/3 × π × 27 = 36π cm³.
Choose an option to check your answer.
Square area is side squared.
Thus, 9² = 81 cm².
Choose an option to check your answer.
The edge length is the cube root of the volume.
Since 6³ = 216, the edge is 6 cm.
Choose an option to check your answer.
The side length is √144 = 12 cm.
The perimeter is 4 × 12 = 48 cm.
Choose an option to check your answer.
Distance is √[(3 - 0)² + (4 - 0)²].
This equals √25 = 5.
