Question

The dimension of a cuboid are 7cm, 11cm & 13cm, The total surface area is ​

Answer 1

Answer:

Given :

• ➨ Length of the cuboid = 7cm
• ➨ Breadth of the cuboid = 11cm
• ➨ Height of the cuboid = 13cm

$\begin{gathered} \end{gathered}$

To Find :

• ➨ The total surface area of a cuboid when the information is given there = ?

$\begin{gathered} \end{gathered}$

Explanation :

Now, here is the provided information about the length, Breadth and height of the cuboid. But, we have to find here the total surface area of the cuboid –

• ➻ Length of the cuboid = 7cm
• ➻ Breadth of the cuboid = 11cm
• ➻ Height of the cuboid = 13cm

So, we will apply an appropriate formula to find the solution for the provided question –

$\begin{gathered} \end{gathered}$

Formula Used :

$\large{\bigstar{\underline{\boxed{\sf{2(lb + bh + lh) }}}}}$

$\begin{gathered} \end{gathered}$

Solution :

Therefore, as per the provided formula we will substitute the value for finding the solution of this question –

⟹ 2(lb + bh + lh)

⟹ 2(7 × 11 + 11 × 13 + 7 × 13)

⟹ 2 × (77 + 143 + 91)

⟹ 2 × 311

⟹ 622 cm²

Hence, the total surface area of a cuboid with the provided information is given = 248 cm².

$\rule{200pt}{2.5pt}$

Answer 2

Given :

➨ Length of the cuboid = 7cm

➨ Breadth of the cuboid = 11cm

➨ Height of the cuboid = 13cm

\begin{gathered} \end{gathered}

To Find :

➨ The total surface area of a cuboid when the information is given there = ?

\begin{gathered} \end{gathered}

Explanation :

Now, here is the provided information about the length, Breadth and height of the cuboid. But, we have to find here the total surface area of the cuboid –

➻ Length of the cuboid = 7cm

➻ Breadth of the cuboid = 11cm

➻ Height of the cuboid = 13cm

So, we will apply an appropriate formula to find the solution for the provided question –

Formula Used :

★ 2(lb + bh + lh)

Solution :

Therefore, as per the provided formula we will substitute the value for finding the solution of this question –

⟹ 2(lb + bh + lh)

⟹ 2(7 × 11 + 11 × 13 + 7 × 13)

⟹ 2 × (77 + 143 + 91)

⟹ 2 × 311

⟹ 622 cm²

Hence, the total surface area of a cuboid with the provided information is given = 248 cm².
