Exam-Style Question on Volume
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 349. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.
The diagram shows a rectangular-based pyramid, TABCD (not drawn to scale).
The horizontal base ABCD has sides of lengths 11m and 15m. The centre of the base of the pyramid is M.
Angle TMC is 90° and angle TCM is 70°
The volume of a pyramid is \( \frac13 \) × area of base × perpendicular height. Calculate the volume of this pyramid.
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
