Question

Find the total surface area of cuboid having sides are 9cm ,15cm and 19 cm​

Answer 1

Answer:

Total surface area=1,182 $cm^{2}$

Step-by-step explanation:

Given: L=9cm

           B=15 cm

           H=19 cm

Total Surface area of cuboid = 2(lb + bh + hl)

where, l stands for length of the cuboid, b stands for breadth of the cuboid and h stands for height of the cuboid.

Total surface area of cuboid=2[(9×15)+(15×19)+(19×9)]

⇒2(135+285+171)

⇒2(591)

Total surface area=1,182 $cm^{2}$
