1.1.1. total mass = 6 x 110g= 660 g
1.1.2. radius = diameter ÷2 = 64÷2= 32 mm
1.1.3. A. 𝑚𝑚3
1.1.4. number of days= 21+28+31 = 80 days
1.1.5. 6 pringles cost R100
100
2 pringles = 𝑥2 = 𝑅33.33
6
1.2.1. A
1.2.2. D
1.3.1. longest dimension = 7.3 m = 7.3 x100 = 730 cm
1.3.2. missing length, D = 7.3 -5.2 = 2.1 m
1.3.3. height = 0.5 m
1.4.1. A layout plan shows the layout of buildings or structures. It shows an object as seen
from above, as if you have taken off the roof of the building/structure to look inside.

2.7.2. unable to give an exact answer here since physically measuring will give everyone a slight
different answer, the method will be given below
step 1: measure length of bedroom in cm using ruler
step 2: convert to real life measurement by multiplying value above by 1000, you will then have an
answer in mm
step 3: convert to meters by dividing by 1000
2.7.3. the floor plan can become reduced or enlarged when photocopying resulting in inaccuracies.
Question 3
3.1.1. outside width, A= inside width + 2x thickness = 162 +1.5 +1.5 =165 cm
3.1.2. B = outside height –inside height of bottom shelf- bottom shelf width – 2x top shelf thickness =
B=80-40-4.5-2(1.5) = 32.5 cm
3.2. outside height = 80cm = 31.496 inches
1 inch = 80/31.496 = 2.54 cm
1 inch =2.54 cm
3.3.1. length of backboard= A = 165 cm
Width of backboard =80cm
Area of backboard= 165 x 80= 13 200 𝑐𝑚2
3.3.2. 𝑐𝑚2 → 𝑚2 (divide by 1002 = 10000)
13 200
