MATH QUESTION
The volume of a square-based pyramid is 223 cm3.
The height of this pyramid is 12 cm.
12 cm
Rounded to the nearest tenth,
what is the length of a side of
the base of this pyramid?
A) 4.3 cm
C) 13.9 cm
B) 7.5 cm
D) 29.9 cm
ANSWER: B
MATH SOLUTION
Vpyramid =
223 =
B h
3
B 12
3
12B = 3(223)
12B = 669
B = 55.75
 Length of a side of the base =
55.75  7.5 cm
Answer: Rounded to the nearest tenth, the length of a side of the
base of this pyramid is 7.5 cm.
SCIENCE QUESTION
A calorimeter was used to heat 500 mL of water to 100°C.
If the thermal energy provided was equal to 167 600 J,
what was the temperature of the water before it was
heated?

Determining the initial temperature
T = Tf  Ti
Ti = Tf  T
Ti = 100°C  80°C = 20°C
Answer: The temperature of the water before it was heated was 20°C.

Using the KMWC model for problem solving
READING A PROBLEM – KMWC TIPS
K : What facts do I KNOW from the information in the problem?
M : Can I MODEL the situation with a picture or manipulatives?
W : WHAT does the problem ask me to find?
C : CROSS OUT any facts that are not needed.
READING A PROBLEM – KMWC TIPS
An air traffic controller was monitoring two airplanes. He
noticed that as plane A began its descent in order to land,
plane B left the ground.
When plane A began its descent, it was flying at an altitude
of 900 metres. During its descent, its altitude decreased at
a rate of 4 metres per second.
As soon as plane B took off, its altitude increased at a rate
of 5 metres per second.
At a certain point in time, both planes were at the same
altitude. Then, exactly 10 seconds later, the air traffic
controller switched to the radar in order to monitor plane B.
What altitude had plane B reached when radar monitoring
began? Show all your work.

K:
What facts do I KNOW from the information in the
problem?
“What words or ideas don’t I understand?”
M:
Can I MODEL the situation with a picture or manipulatives?
“Is there any missing information that I can estimate?”
W:
WHAT does the problem ask me to find?
C:
CROSS OUT any facts that are not needed.
