Surface Area, Nets, and 3D shapes

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 surface area of a rectangular prism?

Back

The surface area is calculated by the formula: SA = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

Front

What is the difference between a prism and a pyramid?

Back

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

Front

How many faces does a cube have?

Back

A cube has 6 faces.

Front

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

Back

The surface area is calculated by the formula: SA = B + 1/2 * P * l, where B is the area of the base, P is the perimeter of the base, and l is the slant height.

Front

What is a triangular prism?

Back

A triangular prism is a three-dimensional shape with two triangular bases and three rectangular faces.

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is found using the formula: Area = length × width.

Front

What is the volume of a cube?

Back

The volume of a cube is calculated using the formula: V = s³, where s is the length of a side.

Front

What is a base in the context of 3D shapes?

Back

A base is the bottom surface of a three-dimensional shape, which can be flat or curved.

Front

How many edges does a triangular prism have?

Back

A triangular prism has 9 edges.
