Area is measured in which kind of units?

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

Correct answer: D. Square units

1. Area is the two dimensional space inside the boundary of a flat object. 2. Two dimensions means two lengths multiplied together. 3. Area is therefore measured in square units. 4. Volume takes up three dimensions and so is measured in cubic units instead. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 13: Measurements_

How is the volume of a right prism or a cylinder calculated?

  1. Base area times height
  2. Base area plus height
  3. Base area over height
  4. Base edge times height
Show answer and solution

Correct answer: A. Base area times height

1. A right prism has the same shape and size all the way from base to top. 2. Its volume is found by multiplying the area of the base by the height of the solid. 3. A cylinder follows the same rule, with a circle as its base. 4. Using only one edge of the base instead of the whole base area misses a dimension, so that answer is too small. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 13: Measurements_

A cube is unfolded flat into its net. What does the net consist of?

  1. Four identical squares
  2. Six identical squares
  3. Eight identical squares
  4. Nine identical squares
Show answer and solution

Correct answer: B. Six identical squares

1. A net is what you get when a solid is unfolded so that every face can be seen. 2. A cube unfolded into a net is made up of six identical squares. 3. Adding the areas of those six squares gives the surface area of the cube. 4. A triangular prism unfolds into two triangles and three rectangles, which is a different net. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 13: Measurements_
