Question

find the surface area of a cubical box whose one side is 80cm

Answer 1

The surface area is of two type: lateral(LSA) and total (TSA)

LSA of cube is sum of areas of four faces of cube

i.e LSA = 4*area of each face

            = 4* (80)²

            = 25600 cm²

TSA of cube = LSA + area of top and bottom faces

                    = 25600 + 2(80)²

                    = 38400 cm²

Answer 2

WE NEED TO FIND TSA AND LSA FOR THIS.
