To find the surface area of a rectangular pyramid, we need to calculate the area of each face and add them together.

First, let's find the area of the base. The base of the pyramid is a rectangle, so the area is length × width = 13 cm × 11 cm = 143 cm².

Next, let's find the areas of the four triangular faces. Each triangular face has a base equal to the length of the rectangle (13 cm) and a height equal to the height of the pyramid (8 cm). So each triangular face has an area of 1/2 × base × height = 1/2 × 13 cm × 8 cm = 52 cm².

There are four triangular faces, so the total area of the triangular faces is 4 × 52 cm² = 208 cm².

Finally, to find the surface area of the pyramid, we add the area of the base and the area of the triangular faces: 143 cm² + 208 cm² = 351 cm².

So, the surface area of the rectangular pyramid is 351 cm², rounded to the nearest hundredth.

Answer 8

what is the surface area of a square pyramid with a base length of 10 cm and a slant height of 20 cm

Answer 9

[AI-generated answer — Bot GPT 3.5]

To find the surface area of a square pyramid, we need to calculate the area of the base and the area of the four triangular faces and then add them together.

First, let's find the area of the base. The base of the pyramid is a square, so the area is length × width = 10 cm × 10 cm = 100 cm².

Next, let's find the area of the four triangular faces. Each triangular face has a base equal to the length of the square (10 cm) and a height equal to the slant height of the pyramid (20 cm). So each triangular face has an area of 1/2 × base × height = 1/2 × 10 cm × 20 cm = 100 cm².

There are four triangular faces, so the total area of the triangular faces is 4 × 100 cm² = 400 cm².

Finally, to find the surface area of the pyramid, we add the area of the base and the area of the triangular faces: 100 cm² + 400 cm² = 500 cm².

So, the surface area of the square pyramid is 500 cm².
