Using the assumed values, Christi should use 494.10 square units of the gift wrap
How to determine the amount of gift wrap?
To do this, we simply calculate the surface area of the gift wrap.
This is calculated using:
[tex]A= 5ah + 0.5a^2 * \sqrt{5(5 + 2\sqrt{5})[/tex]
Assume that
a = 10 and h = 3;
The equation becomes
[tex]A= 5 * 10 * 3 + 0.5 * 10^2 * \sqrt{5(5 + 2\sqrt{5})[/tex]
Evaluate
A= 494.10
Hence, Christi should use 494.10 square units of the gift wrap
