Question

If a cuboidal box has height, length and width as 20 cm, 15 cm and 10 cm. Then its total surface area in sq. cm is???

Answer 1

Answer:

$1300cm^{2}$

Step-by-step explanation:

Given :

length is 20cm

breadth is 15cm

height is 10cm

Solution:

Given that , length breadth and height is 20cm , 15cm ,and 10cm of cuboid then we have to find the total surface area of cuboid

As we know that :

Total surface area of a cuboid is 2(lb + bh + hl)

where l is length 20cm , b is breadth 15cm and h is height 10 cm

Then,

⇢ 2 (20 × 15 + 15 × 10 + 10 × 20)

⇢ 2(300 + 150 + 200)

⇢2(650)

⇢ 1300cm²
