Worked practice questions

What is a solid called once it has been unfolded flat?

  1. A net
  2. A face
  3. An edge
  4. A prism
Show answer and solution

Correct answer: A. A net

1. Picture a cardboard box being opened out until it lies flat. 2. A solid that is unfolded like this is called a net. 3. Each face of the solid can then be seen clearly and its area worked out. _Source: Siyavula Mathematics Grade 11 (Everything Maths, CC BY 4.0), Chapter 7: Measurement_

Volume is measured in which kind of units?

  1. Square units
  2. Cubic units
  3. Linear units
  4. Angle units
Show answer and solution

Correct answer: B. Cubic units

1. Volume is the three dimensional space taken up by an object. 2. Three dimensions are multiplied together, so volume is measured in cubic units. 3. Surface area covers only two dimensions, so it is measured in square units. _Source: Siyavula Mathematics Grade 11 (Everything Maths, CC BY 4.0), Chapter 7: Measurement_

A right prism has a polygon as its base. How do its sides stand?

  1. Slanted towards the base
  2. Perpendicular to the base
  3. Parallel to the base
  4. Curved around the base
Show answer and solution

Correct answer: B. Perpendicular to the base

1. A right prism has a polygon as its base. 2. Its vertical sides stand perpendicular to that base. 3. It is called a right prism because those angles between base and sides are right angles. 4. The base and the top surface are the same shape and the same size. 5. Sides that slant instead of standing upright belong to a pyramid, not a right prism. _Source: Siyavula Mathematics Grade 11 (Everything Maths, CC BY 4.0), Chapter 7: Measurement_
