Question

Length, breadth and height of a cuboid shape box of medicine is 20cm, 12 cm and 10 cm respectively. Find the surface area of vertical faces and total surface area of this box.

Answer 1

I hope this is correct.

Answer 2

Answer:

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 cm²
