Question

Find the total surface area of cuboid whose length is 10cm, breadth is 8cm and height is 6cm ?​

Answer 1

Answer :-

• The total surface area of cuboid is 376cm²

Step-by-step explanation:

To Find:-

• The total surface area of cuboid

Solution:

Given that,

• Length of cuboid = 10cm
• Breadth of cuboid = 8cm
• Height of cuboid = 6cm

We know that,

Total surface area of cuboid = 2(lb+bh+hl) sq. units,

Where,

• l = length
• b = breadth
• h = Height

Therefore,

⟼ 2 ( lb + bh + hl )

⟼ 2 ( 10*8 + 8*6 + 6*10 )

⟼ 2 ( 80 + 48 + 60 )

⟼ 2 ( 128 + 60 )

⟼ 2 ( 188 )

⟼ 2*188

⟼ 376cm²

Hence, The total surface area of cuboid is 376cm².

Formula used:

Total surface area of cuboid = 2 ( lb + bh + hl ) sq. units

Where,

• l = Length
• b = Breadth
• h = Height

Answer 2

${\boxed{\underline{\tt{\orange{Required \: Answer:-}}}}}$

★GIVEN:-

• Length = 10cm

• Breadth = 8cm

• Height = 6cm

★TO FIND:-

• Total surface area of cuboid.

★FORMULA USED:-

• TSA of Cuboid is A = 2( lb + bh + hl )

where,

⇢ l is length = 10 cm

⇢ b is breadth = 8 cm

⇢ h is height = 6 cm

★SOLUTION:-

Substitute the value in thw formula:-

⇝.A = 2( 10 × 8 + 8 × 6 + 10 × 6)

⇝ A = 2( 80 + 48 + 60)

⇝ A = 2(188)

⇝ A = 376

Therefore, the total surface area of a cuboid is 376 square centimeter.
