Question

Find the total surface area of cuboid with measures 10 cm, 6 cm, 8 cm​

Answer 1

Answer:

Total surface area of a cuboid is 376 square cm

Step-by-step explanation:

Given : A cuboid of length 10 cm breadth 8 cm and height 6 cm.

To find : The total surface area of a cuboid?

Solution :

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

Where, l is the length l = 10 cm

b is the breadth b = 8 cm

h is the height h = 6 cm

Substitute the value in the formula,

A = 2(10*8 + 8*6 + 6*10)

A = 2(80 + 48 + 60)

A = 2(188)

A = 376

Answer 2

Given :

• The dimensions of the cuboid are 10cm, 6cm, 8cm

Objective :

• To find the total surface area of the cuboid

Formula Used :

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

Solution :

We know that ,

$\: \: \: \: \: \: \star { \underline{\boxed{ \pmb{ \sf{T S A = 2(lb + bh + hl)}}}}}$

Where,

• l = length
• b = breadth
• h = height

here,

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

Substituting the values ,

$\rightarrow \sf TSA_{(cuboid)} = 2(lb+bh+hl)$

$\rightarrow\sf TSA_{(cuboid)} = 2(10(6) + 6(8) + 8(10))$

$\rightarrow\sf TSA_{(cuboid)} = 2(60 + 48 + 80)$

$\rightarrow\sf TSA_{(cuboid)} = 2(188)$

$\rightarrow\sf TSA_{(cuboid)} = 376m^2$

Therefore :

• The TSA of the cuboid is 376m²

More to know :

• Volume of cuboid = lbh
• LSA of cuboid = 2h(l+b)
• Volume of cube = edge³
• TSA of cube = 6 (edge)²
• LSA of cube = 4 (edge)³
