Question

Lateral surface area of cuboid with dimensions :length 9 cm, breadth 7cm and height is 3 cm is..?​

Answer 1

To Find :

The Lateral surface area of the Cuboid .

Given :

• Length = 9 cm

• Height = 3 cm

• Breadth = 7 cm

We Know :

Lateral Surface Area of a Cuboid :

$\bf{\underline{\boxed{LSA = 2(l + b)h}}}$

Where :-

• LSA = Lateral surface Area

• l = Length

• b = Breadth

• h = Height

Solution :

Using the formula and substituting the values in it , we get :

$\implies \bf{LSA = 2(l + b)h} \\ \\ \\ \implies \bf{LSA = 2(9 + 7)3} \\ \\ \\ \implies \bf{LSA = 2 \times 10 \times 3} \\ \\ \\ \implies \bf{LSA = 60 cm^{2}} \\ \\ \\ \therefore \purple{\implies \bf{LSA = 60 cm^{2}}}$

Hence , the Lateral surface of the Cuboid is 60 cm².
