Acandle in the shape of a right pyramid with a square base that has an area of 144 inches. the slant height of the candle is 10 inches. what is the total area of the candle?

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

Let us find first side of the square base.

Side of the square base =

Side of the square base =

Perimeter of the square base = 4 × side = 4 × 12 = 48 inches.

Slant height = 10 inches.

Total area of right pyramid with a square base = Area of square base + 1/2( perimeter of the base × slant height).

Total area of right pyramid with a square base = 144 + 1/2 (48 × 10)

                                                                              = 144 + 1/2 ( 480)

                                                                              = 144 + 240

                                                                              = 384 square inches.
