Geometry 11.7 Composite Surface Area

Front

What is composite surface area?

Back

The total area of all the surfaces of a composite figure, which is made up of two or more simple geometric shapes.

Front

How do you calculate the surface area of a rectangular prism?

Back

Find the area of all six faces and sum them up: Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the formula for the surface area of a cylinder?

Back

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

Front

How do you find the surface area of a square pyramid?

Back

Surface Area = Base Area + 1/2 * Perimeter of Base * Slant Height.

Front

What is the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

How do you find the surface area of a cone?

Back

Surface Area = πr(r + l), where r = radius and l = slant height.

Front

What is the first step in calculating the composite surface area of a figure?

Back

Identify and calculate the surface area of each individual shape that makes up the composite figure.

Front

What is the importance of finding the surface area in real-life applications?

Back

Surface area calculations are essential in fields like construction, manufacturing, and packaging to determine material needs.

Front

How do you find the surface area of a triangular prism?

Back

Surface Area = (Base Area) + (Perimeter of Base * Height).

Front

What is the formula for the surface area of a cube?

Back

Surface Area = 6a², where a = length of a side.
