The base of a pyramid has n sides.<br> Write an EXPRESSION for the number of faces of the pyramid.

ser-zykov [4K]

<span>In general, if the pyramid has 'x' sides, then it will have 'x' lateral faces. Total Number of Faces = Number of Base Faces + Number of Lateral Faces. Total Number of Faces = 2 + x. So the formula is F=x%2B2 where "x" is the number of sides that the pyramid has and "F" is the total number of faces.</span>

Sonya wants to sew ribbon along each side of a square pillow.

Eduardwww [97]

We are given area of the ribbon = 144 square inches.

We know formula for side of a square = $\sqrt{Area \ of \ a \ square }$ .

Plugging value of area in the formula, we get

Side of the square $= \sqrt{144}$

= 12 inches.

Sonya wants to sew ribbon along each side of a square pillow.

So, we need to find the perimeter of the square pillow.

<h3>Perimeter = 4 × side = 4 × 12 = 48 inches.</h3><h3>Therefore, she buy 48 inches of ribbon to have the exact amount that she needs.</h3>
