PolarNik [594]

Akira needs 45 square inches of gold foil to cover the chair free including the bottom

Step-by-step explanation:

Total surface = surface area of the base square + area of 4 triangles

Step 1: The surface area of the base square

surface area of the base = surface area of the square =

where s is the side length

The the surface area of the base = = 9 square inches

Step 2: The surface area of the side triangles

The area of the triangle =

On substituting the values,

The area of the triangle =

The area of the triangle =

The area of the triangle = 9 square inches

Now the area of 4 triangles = 4 x 9 = 36 square inches

Thus the total surface area = 9 + 36 = 45 square inches
