Answer 1

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

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* Width +Width* Height + Height* Length)`

Substituting the given value in above formula we will get

`\textrm{Surface Area of Cuboid}= 2(8* 8 + 8* 10 + 10* 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 .
