A cube is a threedimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Surface Area of a Cube is the measure of how much exposed area a cube has and it is measured in square units. 
Observe the side length of a cube and name it as 'a'
Apply the formula: Surface area of a cube = 6a^{2}
Calculate the surface area of a cube with a side of length 4 cm?
Given side length = 4cm
Surface area of a cube = 6a^{2}
Surface area of a cube = 6(4cm)^{2}
Surface area of a cube = 6(16cm^{2})
Surface area of a cube = 96 cm^{2}
96 cm^{2}
Calculate the surface area of a cube with a side of length 6 cm?
Given side length = 6cm
Surface area of a cube = 6a^{2}
Surface area of a cube = 6(6cm)^{2}
Surface area of a cube = 6(36cm^{2})
Surface area of a cube = 216 cm^{2}
216 cm^{2}
