closest centimeter)
4. Use a formula to determine the area of the following polygons. Show your work.
5. A fire truck box is built to fit in a section of the fire truck. It is used to store fire hoses.
There are three compartments each measuring 122cm long, 89cm wide, and 67cm high.
Use a formula to determine the volume of each compartment. What is the total volume of
the fire truck box?

6. Look at the illustrations of the two swimming pools. Determine how much fencing needs
to be purchased for each pool. Determine how large the cover for each pool needs to be
and figure out the amount of water needed for each pool. What do you notice? Show
your work including the formulae you have used.

7. Prove the following statements with an illustration and an explanation.
a) For any two right rectangular prisms, the one with the greater volume will be the prism
that has the greatest base area.
b) For any two rectangles, the rectangle with the greatest perimeter will also have the greatest
area.

Teacher Notes: Students will need a centimeter ruler and a calculator would be beneficial for number 3
as we are not testing the operations.

Area, volume
20 cm
Perimeter: Square- P= 4(s) or similar formula
=4x4
= 16cm
Rectangle P= 2 (l+w) or similar formula
= 2 (6+4)
= 2 x 10
= 20cm
Area: Square- Area= 4(s)
=4x4
= 16cm²
Rectangle Area= l x w
=5x3
= 15cm²
Volume: V= l x w x h
= 122 x 89 x 67
= 727 486cm³
Total volume= 727 486 x 3
= 2 182 458 cm³
Fencing: 32m
Pool cover: 48m²
Water: 72m³
Students should notice that the orientation of the pool does not change
the perimeter, area or volume. Students should show formulas used.
Answers will vary.
