Solids: surface area and volume
Volume and surface areas of a cube, cuboid, cylinder, cone, sphere and hemisphere.
Volume = 1540, curved surface = 440, total surface = 748
The working
- Volume = 22/7r²h = 3.1429 × 7² × 10 = 1540.
- Curved surface = 222/7rh = 2 × 3.1429 × 7 × 10 = 440.
- Total surface = curved + two circles = 440 + 222/7r² = 748.
