3D Geometry: Volume and Surface Area with Fully Worked Solutions
This Geometry worksheet is a high-quality, exam-focused resource designed for middle to early secondary school learners (Grades 6–9), typically ages 11–15. It systematically covers core 3D geometry topics—volume and surface area of cuboids, prisms, pyramids, and composite solids—using clear diagrams, correct formulas, and fully worked step-by-step solutions. The layout mirrors GCSE (UK – Pearson Edexcel, AQA, OCR) and Cambridge IGCSE / O-Level (CAIE) exam standards, while also aligning well with Key Stage 3, CBSE, and international school curricula. Each question models proper mathematical reasoning, unit handling, and exam presentation, making it ideal for classroom teaching, revision packs, mock exams, homeschooling, and tutoring. Teachers can confidently use this as a ready-to-teach assessment resource, while students benefit from concept clarity and exam confidence through structured solutions and visual support.
