Answer 1

Answer:

Therefore, 448 inches² Wrapping paper is needed to wrap a present.

Step-by-step explanation:

The Present Shape as per dimensions it is CUBOID

Given:

Length = 8 inches

Width = 8 inches

Height = 10 inches

To Find:

Surface Area of Cuboid = ?

( Wrapping paper is needed to wrap a present )

Solution:

By Formula we have

$\textrm{Surface Area of Cuboid}= 2(Length\times Width +Width\times Height + Height\times Length)$

Substituting the given value in above formula we will get

$\textrm{Surface Area of Cuboid}= 2(8\times 8 + 8\times 10 + 10\times 8)\\\\\textrm{Surface Area of Cuboid}= 2(224)\\\\\textrm{Surface Area of Cuboid}= 448\ inches^{2}$

Therefore, 448 inches² Wrapping paper is needed to wrap a present .
