Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra
mina [271]

Answer:

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

<u>Step-by-step explanation:</u>

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

<u>Step 1: The surface area of the base square</u>

surface area of the base = surface area of the square =  s^2

where s is the side length

The the surface area of the base  = 3^2 = 9 square inches

<u>Step 2: The surface area of the side triangles </u>

The area of the triangle = \frac{1}{2}\times \text{side length} \times \text{slant height}

On substituting the values,

The area of the triangle =\frac{1}{2} \times 3 \times 6

The area of the triangle = \frac{18}{2}

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
