Finding Surface Area of Prisms and Pyramids

Front

What is surface area?

Back

The sum of all the areas of all the shapes that cover the surface of the object.

Front

Name this figure: A pyramid with a square base.

Back

Square Pyramid

Front

Find the surface area of a cube with side length 12 m.

Back

864 m²

Front

What is the total surface area of the shape shown? (Assuming the answer is 260)

Back

260

Front

How do you find the AREA of a TRIANGLE?

Back

Base x Height divided by 2

Front

What is the formula for the surface area of a rectangular prism?

Back

2(lw + lh + wh) where l = length, w = width, h = height.

Front

What is the formula for the surface area of a square pyramid?

Back

(Base Area) + (1/2 * Perimeter of Base * Slant Height)

Front

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases, while a pyramid has one base and triangular faces that meet at a point.

Front

How do you calculate the surface area of a cylinder?

Back

2πr(h + r) where r = radius and h = height.

Front

What is the surface area of a triangular prism with a base area of 20 m², height of 10 m, and perimeter of the base of 30 m?

Back

Surface Area = 2(20) + (30 * 10) = 40 + 300 = 340 m².
