Q.13 Find the total surface
area of the cuboid. I=5cm,
b=3.5cm, h=1.4cm
Answers
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.
