NSC Mathematical Literacy Measuring length: Sifiso is a builder who uses bui

Question

Sifiso is a builder who uses building plans and measuring instruments.

Some measuring instruments and scales used by builders are shown below.

Choose an item from COLUMN B that matches a description in COLUMN A. Write only the letter (A–G) next to the question numbers (1.1.1 to 1.1.5) in the ANSWER BOOK.

**COLUMN A**
1.1.1 The most appropriate scale to draw a map of South Africa  
1.1.2 The instrument most suited to measure the circumference of a dinner plate  
1.1.3 The most appropriate scale to draw a plan of a house  
1.1.4 The instrument most suited to measure the width of a soccer field  
1.1.5 The instrument most suited to measure the length of a pencil

**COLUMN B**  
A 0 – 100  
B A protractor  
C A scale of 1:500  
D A tape measure  
E A ruler  
F A clinometer  
G 1 cm = 1 m (5 × 2)

The sketch below shows a standard brick, with dimensions, used in South Africa.

**SKETCH OF A STANDARD BRICK**  
Dimensions of the Brick  
Height = 70 mm  
Width = 112 mm  
Length = 240 mm

Use the information below to answer the questions that follow.

1.2.1 State which formula (A, B or C) can be used to calculate the total surface area (TSA) of the given brick.  
A  TSA(brick) = Area of front side + Area of right-hand side + Area of top  
B  TSA(brick) = (2 × 240 × 70) + (2 × 240 × 112) + (2 × 112 × 70)  
C  TSA(brick) = (240 × 70 × 112 + 70) mm²

1.2.2 State the unit of measurement for the volume of this brick.

1.2.3 Calculate the length of this brick.

1.2.4 Determine the maximum number of rows of bricks that can be stacked height-wise to a height of 2 100 mm.

Maria uses the recipe below to bake scones.

**Ingredients (makes 1 dozen)**  
75 g butter  
2 large eggs  
75 g sugar  
4 teaspoons baking powder  
230 ml milk  
500 g flour  
1 cup raisins

**Baking Instruction**  
Bake for 15 minutes at 200 °C.

Use the information above to answer the questions that follow.

1.3.1 Convert the mass of the flour to kilograms.

1.3.2 Determine the number of large eggs needed to make 30 scones.

1.3.3 Each scone has an average diameter of 7 cm.

1.3.4 Calculate how many full dozen scones can be made with 500 g of butter.

1.3.5 The scones are placed in the oven at 14:10.

1.3.6 Write down, in words, the time the scones were placed in the oven.
