N4 Revision Surface Area E&F
Example 1 Surface area Surface area The Surface Area of a cube is the area of all 6 faces added together : In a Cube all 6 faces are the same size: 20cm 20cm Area of 1 face = l x b 20cm 20cm 20cm 20cm = 20 x 20 = 400 cm Total Surface Area = 6 x 400= 2400cm
Example 2 Surface area Surface area The Surface Area of a cube is the area of all 6 faces added together : In a Cube all 6 faces are the same size: 3.5cm 3.5cm Area of 1 face = l x b 3.5cm 3.5cm 3.5cm 3.5cm = 3.5 x 3.5 = 12.25 cm Total Surface Area = 6 x 12.25= 73.5cm
Exercise 1 Find the Surface Area of the following cubes: 384cm 384cm2 2 600cm 600cm2 2 7350cm 7350cm2 2 864cm 864cm2 2 Side 8cm Side 8cm Side 10cm Side 10cm Side 35cm Side 35cm Side 12cm Side 12cm 496.86cm 496.86cm2 2 13.5cm 13.5cm2 2 1944cm 1944cm2 2 18150cm 18150cm2 2 Side 9.1cm Side 9.1cm Side 1.5cm Side 1.5cm Side 18cm Side 18cm Side 55cm Side 55cm
Example 3 Surface area Surface area The Surface Area of a cuboid is the area of all 6 faces added together : In a Cuboid: Front face =Back Face Top face= Bottom Face Left side = Right Side 55cm 55cm 20cm 20cm 30cm 30cm = l x b = 30 x 20 Area Top Area Left = l x b Area Front = l x b = 30 x 55 = 55 x 20 = 600 cm = 1650 cm = 1100 cm Left&Right = 2200cm2 Top&Bottom=1200cm2 Front&Back=3300cm2 Total Surface Area = 3300 + 1200 + 2200= 6700cm
Example 4 Surface area Surface area The Surface Area of a cuboid is the area of all 6 faces added together : In a Cuboid: Front face =Back Face Top face= Bottom Face Left side = Right Side 13m 13m 8m 8m 5m 5m = l x b = 5 x 8 Area Top Area Left = l x b Area Front = l x b = 13 x 5 = 13 x 8 = 40 m = 65 m = 104 m Left&Right = 208m2 Top&Bottom=80m2 Front&Back=130m2 Total Surface Area = 130 + 80 + 208= 418m
