Question

Find the total surface area and lateral surface area of the cuboid which is 5.5m long 5m broad and 4.2 m high​

Answer 1

Given,

length of the cuboid = 5.5 m

Breadth of the cuboid = 5 m

Height of the cuboid = 4.2 m

Total Surface Area = 2 ( lb + bh + hl )

⇏2 ( 5.5 × 5 + 5 × 4.2 + 4.2 × 5.5 )

⇏2 ( 27.5 + 21 + 23.1 )

⇏2 ( 71.6 )

⇏143.2 m²

Lateral Surface Area = 2h ( l + b )

⇏2 × 4.2 ( 5.5 + 5 )

⇏8.4 × 10.5

⇏88.2 m²
