Question

find the total surface area and the lateral surface area of a cuboid whose dimensions are , length =16m , breadth = 12m , height = 8.5m.

Answer 1

Answer:

Total surface area of the cuboid is m² and lateral surface area of the cuboid is m².

Step-by-step explanation:

Given :-

Length of cuboid = 16 m

Breadth of cuboid = 12m

Height of cuboid = 8.5m

To find :-

Total surface area (TSA) and Lateral surface area (LSA) of cuboid.

Solution :-

Formula used :

• ${\boxed{\sf{TSA\:of\: cuboid=2(l\times\:b+b\times\:h+l\times\:h)}}}$

TSAofcuboid=2(l×b+b×h+l×h)

• ${\boxed{\sf{LSA\:of\: cuboid=2h(l+b)}}}$

LSAofcuboid=2h(l+b)

Here,

l = length

b = breadth

h = height

TSA of cuboid,

= 2(l×b+b×h+l×h)

= 2(16×12+12×8.5+16×8.5)m²

= 2(430)m²

= 2 × 430 m²

= 860m²

Total surface area of cuboid is 860m².

LSA of cuboid,

= 2h(l+b)

= 2×8.5(16+12) m²

= 17(28)m²

= 17×28m²

= 476m²

Lateral surface area of cuboid is 476m².
