13.1 - 13.3 Recap: Surface Area, Nets, and 3D shapes

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

How many bases does a pyramid have?

Back

One.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

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

Back

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

Front

How many faces does a prism have?

Back

A prism has two bases and additional rectangular faces connecting the bases.

Front

What is the total surface area of a cylinder?

Back

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

Front

What is the difference between a pyramid and a prism?

Back

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

Front

What does total surface area include?

Back

Total surface area includes all the faces of a 3D shape, including the bases.

Front

How do you find the area of a rectangle?

Back

Area = length × width.

Front

What is the surface area of a cube?

Back

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