Question

If a cuboidal box has height, length and width as 20 cm, 15 cm and 10 cm
respectively. Then its total surface area is:
​

Answer 1

Answer:

1300 cm^2

Step-by-step explanation:

total surface area of cuboid is

2( lb + bh + hl )

length = 15cm

breadth = 10cm

height = 20cm

Therefore,

= 2 [ (15×10) + (10×20) + (20×15) ]

= 2 ( 150 + 200 + 300 )

= 2 × 650

= 1300 cm^2
