Ajay wraps a gift box in the shape of a triangular pyramid. The amount
of wrapping paper he uses is 173.2 square inches.
<h3>How to calculate the surface area of a triangular pyramid?</h3>
The formula for calculating the total surface area is expressed as:
Area = 4(area of triangle)
The area of the triangle
A = 0.5(8.66)(10)
A = 43.3 square inches
The total surface area will be
TSA = 4(43.3)
TSA = 173.2 square inches
Hence the amount of wrapping paper Ajay uses is 173.2 square inches
