Math Worksheet – Area, Perimeter and Volume – IGCSE Class 6 and 7 – Cambridge IGCSE Curriculum

Solutions

1. Perimeter: 4 * 6cm = 24cm
2. Area: 10m * 4m = 40m²
3. Area: 5cm * 5cm = 25cm²
4. Volume: 2cm * 2cm * 2cm = 8cm³
5. Perimeter: 2 * (15mm + 8mm) = 46mm
6. LSA of Cuboid: 2 * (4cm + 3cm) * 5cm = 70cm²
7. TSA of Cube: 6 * (7cm * 7cm) = 294cm²
8. Volume of Cuboid: 12cm * 8cm * 5cm = 480cm³
9. Area: 20m * 15m = 300m²
10. TSA of Cuboid: 2 * (6cm * 9cm + 6cm * 2cm + 9cm * 2cm) = 174cm²
11. Perimeter: 28m / 4 = 7m (side length)
12. Combined Area: Area of floor = 10m * 8m = 80m²; Area of rug = 3m * 3m = 9m²; Uncovered area = 80m² – 9m² = 71m²
13. Volume of Irregular Shape: Volume of cube = 5cm * 5cm * 5cm = 125cm³; Volume of prism = 5cm * 5cm * 3cm = 75cm³; Total volume = 125cm³ + 75cm³ = 200cm³
14.     Area of the material Required: 460 cm² (TSA = 700 cm², Top face = 150 cm², so 700 – 150 = 550 cm²)
15.     Height = 6cm
