Question 9

3 marks

A local gift shop sells two types of candle containers. Container A is a rectangular prism with a base area of \( 45 \text{ cm}^2 \) and a height of \( 12 \text{ cm} \). Container B is a rectangular pyramid with the same base area and the same height as Container A.

(a) Find the volume of Container A in \( \text{cm}^3 \).
(b) Find the volume of Container B in \( \text{cm}^3 \).
(c) If a customer fills Container A with sand and then pours it into empty Container B boxes, how many Container B boxes can be filled completely?

Question 10

5 marks

A rectangular aquarium has a length of \( 30 \text{ cm} \) and a width of \( 20 \text{ cm} \). It is filled with water to a depth of \( 15 \text{ cm} \). A solid metal rectangular pyramid with a base measuring \( 10 \text{ cm} \) by \( 12 \text{ cm} \) and a height of \( 15 \text{ cm} \) is placed into the aquarium and is completely submerged.

(a) What is the volume of the metal pyramid?
(b) Find the rise in the water level of the aquarium after the pyramid is submerged.
(c) What is the final height of the water in the aquarium?
