Given:

A cuboid with

  • Length = 5 cm
  • Breadth = 3.5 cm
  • Height - 1.4 cm

What To Find:

We have to find the TSA of the cuboid.

Formula:

TSA of cubiod = (lb + bh + hl)

Where,

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

Solution:

Using the formula,

⇒ TSA  = (lb + bh + hl)

Substitute the values,

⇒ TSA = (5 cm × 3.5 cm + 3.5 cm × 1.4 cm + 1.4 cm × 5 cm)

Multiply the sides,

⇒ TSA = (17.5 cm + 4.9 cm + 7 cm)

Add the sides,

⇒ TSA = 29.4 cm²

Final Answer:

Thus, the TSA of the cuboid is 29.4 cm².
