Question

How much wrapping paper would you need to wrap a rectangular box that is 19 inches by 12 inches by 3 inches?

Answer 1

`642in^(2)`

Explanation:

So, the area of the rectangular box is
`684in^(2)` which means that that's how much wrapping paper you require.

Formula for total surface area:

`2(lb+bh+lh)`

Wherein:

l = length

b = breadth

h = height

Substituting the following values,

`2[(19*12)+(12*3)+(3*19)]`

= 642
