Card 1Cube Properties

How many faces, edges, and vertices does a cube have?

Answer

A cube has: - Faces: 6 (all squares) - Edges: 12 - Vertices: 8 Each face meets 4 other faces, each edge connects 2 vertices, and 3 edges meet at each vertex.

Card 2Cuboid Edges and Length

A cuboid has length = 5 cm, breadth = 3 cm, height = 4 cm. How many edges are there, and what is the total length of all edges?

Answer

Step 1: A cuboid always has 12 edges. Step 2: There are: - 4 edges of length (5 cm) - 4 edges of breadth (3 cm) - 4 edges of height (4 cm) Total length = 4×5 + 4×3 + 4×4 = 20 + 12 + 16 = 48 cm. Ans

Card 3Cube Nets

Which of the following nets can form a cube? (Assume all squares are equal)

Answer

A net can form a cube if it has exactly 6 squares arranged so that: - No more than 4 squares are in a straight line - When folded, each square becomes a face with no overlaps Valid configurations inc

Card 4Oblique Sketching

Draw an oblique sketch of a cube with edge 3 cm.

Answer

Step 1: Use graph paper. Step 2: Draw front face as a square of 3 cm × 3 cm. Step 3: From each corner, draw slanted lines (45°) of 1.5 cm (half for visual effect). Step 4: Draw the opposite face sa

Card 5Cuboid Net

A cuboid is 6 cm long, 4 cm wide, and 2 cm high. Draw its net.

Answer

A net for a cuboid has 6 rectangles: - Two of 6×4 (top and bottom) - Two of 6×2 (front and back) - Two of 4×2 (sides) Arrange them like a cross: - Center: 6×4 (base) - Attach 6×2 above and below - At

Card 6Cylinder Properties

How many faces does a cylinder have? Name and describe them.

Answer

A cylinder has 3 faces: 1. Two flat circular faces (bases) – top and bottom 2. One curved surface (side) There are no vertices and 2 curved edges (where curved surface meets bases). Note: Edges are

Card 7Cone Properties

A cone has one vertex, one edge, and two faces. Explain.

Answer

Yes, this is correct. - Vertex: The pointed top (apex) - Edge: The circular base edge (curved) - Faces: 1 curved surface + 1 flat circular base So: 1 vertex, 1 edge (curved), 2 faces. Unlike polyhed

Card 8Prism Faces

A triangular prism has 5 faces. Describe them.

Answer

A triangular prism has: - 2 triangular bases (top and bottom, congruent) - 3 rectangular side faces (lateral faces) So total = 2 + 3 = 5 faces. It also has 9 edges and 6 vertices.
