# Summary

1. Volume of a cube = (side)^{3}cu. unitsÂ Â

2. Surface area of a cube = 6(side)^{2} sq. units

3. Volume of a cuboid = lbh cu. units

4. Surface area of a cuboid = 2(lb + bh + hl) sq. units

5. Volume of a cylinder = Ï€r^{2}h cu. units

6. Curved surface area of a cylinder = 2Ï€r Ã— h sq. units

7.Â Total surface area of a cylinder = 2Ï€r(r + h) sq. units
