Question 9
5 marks

A rectangular prism (cuboid) has a length of 8 cm, a width of 5 cm, and a height of 10 cm.

(a) Calculate the volume of the prism.

(b) Calculate the total surface area of the prism.

(c) If the cuboid is made of a material with a density of \(2.5 \text{ g/cm}^3\), calculate its mass in kilograms.

Write your answer out first, then check it against the worked solution.

Question 10
6 marks

A solid sphere of radius 6 cm is melted down and all the metal is used to cast identical solid cones. Each cone has a radius of 3 cm and a height of 5 cm.

(a) Calculate the volume of the sphere.

(b) Calculate the volume of one cone.

(c) Determine the maximum number of such cones that can be cast from the metal of the sphere.

(d) If 10% of the metal is wasted during the melting and casting process, how many cones can now be cast? Give your answer as a whole number.

Write your answer out first, then check it against the worked solution.
