MATH 5 PLANE AND SOLID FIGURES

1. What is the name of the solid figure that has a circular base and a curved surface?

• a) Cone

• b) Pyramid

• c) Cylinder

• d) Sphere

Answer explanation

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface

2. How many faces does a cube have?

• a) 4

• b) 6

• c) 8

• d) 12

Answer explanation

A cube has six flat faces, or surfaces. Each face of a cube is shaped like a square.

3. What is the name of the plane figure that has three sides and three angles?

• a) Triangle

• b) Quadrilateral

• c) Pentagon

• d) Hexagon

Answer explanation

A triangle is a closed two-dimensional plane figure with three sides and three angles.

4. Which plane figure has four right angles and four sides of equal length?

• a) Square

• b) Rectangle

• c) Rhombus

• d) Trapezoid

Answer explanation

Square: Four straight sides, four right angles, and all sides have equal length.

5. A ___________is any closed, two-dimensional shape.

• a) quadrilateral

• b) plane figure

• c) figure

• d) solid figure

Answer explanation

A plane figure is a flat, two-dimensional shape that is bounded by a finite number of straight or curved lines. This includes shapes like triangles, quadrilaterals, polygons, and circles.

6. A ______________ is three-dimensional, having length, width and height.

• a) plane figure

• b)solid figure

• c)triangle

• d)quadrilateral

Answer explanation

A solid figure is a three-dimensional object that has length, width, and height. It is a three-dimensional shape that has volume, as opposed to a plane figure which is two-dimensional and has no volume.

7. What shape am I?

I am round with no edges, vertices, or edges.

• a)cylinder

• b)cone

• c)sphere

• d)circle

Answer explanation

A sphere is a three-dimensional shape that is round and has no edges, vertices, or edges. It is a perfect circle in three-dimensional space.

8. What shape am I?

I have 6 faces , 12 edges, and 8 vertices. I have all the same shaped faces. All my edges are the same length.

• a)Square Pyramid

• b)cube

• c)rectangular prism

• d)cone

Answer explanation

A cube is a three-dimensional shape that has:

• 6 faces: all of which are square

• 12 edges: all of which are the same length

• 8 vertices: each of which is a corner of the cube

A cube is a perfect example of a shape with all these characteristics.

9. What shape am I?

I have 12 edges, 8 vertices, and 6 faces. I have both square and rectangular faces.

• a)Rectangle

• b)square pyramid

• c)cube

• d)rectangular prism

Answer explanation

A rectangular prism, also known as a rectangular cuboid, is a three-dimensional shape that has:

• 12 edges: which are the sides of the rectangles

• 8 vertices: which are the corners of the rectangles

• 6 faces: which are rectangles

A rectangular prism can have both square and rectangular faces, depending on the dimensions of the rectangles.

10. What combinations of shapes would you need to create a cube?

• a) 6 square faces

• b) 4 squares and 2 rectangles faces

• c) 6 rectangle faces

• d) 4 rectangles and 2 square faces

Answer explanation

A cube is a three-dimensional shape that has 6 faces, and each face is a square. Therefore, you would need to combine 6 square faces to create a cube.

The other options are not correct because:

• b) 4 squares and 2 rectangles faces: This combination would not form a cube, as the shape would not be uniform.

• c) 6 rectangle faces: This combination would not form a cube, as the shape would not have square faces.

• d) 4 rectangles and 2 square faces: This combination would not form a cube, as the shape would not have uniform square faces.

So, you need only 6 square faces to create a cube!
