<h3>How to calculate the surface area of a prism</h3>
The formula for calculating the total surface area is expressed as:
Area = 4(area of triangle)
Find the area of the triangle
A = 0.5(6)(5.2)
A =3(5.2)
A = 15.6 square inches
TSA = 4(15.6)
TSA = 62.4 square inches
Hence the amount of wrapping paper he uses is 62.4 square inches

Angle OAB is a right angle, since line AB is tangent to the circle at A. Thus, triangle AOB is a right triangle.
Applying the Pythagorean Theorem: 5^2 + 12^2 = |OB|^2
Then |OB|^2 = 13^2, and |OB| = 13.
We find x by subtracting |OC| from 13: 13 - 5 = 8.
Line segment has length 8; x = 8.
