Step-by-step explanation:
the surface area of vertical faces = 640 cm²
total surface area of this box. = 1120 cm²
Step-by-step explanation:
Length, breadth and height of a cuboid shape box of medicine is 20cm, 12 cm and 10 cm respectively.
Surface area of vertical faces = 2 * ( length * height + Breadth * Height)
= 2 * ( 20 * 10 + 12 * 10)
= 2 * (200 + 120)
= 2 * 320
= 640
Surface area of vertical faces = 640 cm²
Total surface Area = Surface area of vertical faces + 2 * Length * Breadth
=> Total surface Area = 640 + 2 * 20 * 12
=> Total surface Area = 640 + 480
=> Total surface Area = 1120 cm
