Surface Area Using Nets

Front

What is surface area?

Back

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

Front

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

Back

To find the surface area of a rectangular prism, use the formula: SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is a net in geometry?

Back

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

Front

How do you calculate the surface area of a pyramid?

Back

The surface area of a pyramid is calculated by adding the area of the base to the area of the triangular faces.

Front

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

Back

The surface area of a triangular prism is given by the formula: SA = bh + (perimeter of base * height), where b is the base area.

Front

What is the total surface area of a cube with side length 4 cm?

Back

The total surface area of a cube is SA = 6s². For s = 4 cm, SA = 6(4)² = 96 cm².

Front

What is the surface area of a cylinder?

Back

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

Front

How do you find the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.

Front

What is the surface area of a sphere?

Back

The surface area of a sphere is calculated using the formula: SA = 4πr², where r is the radius.

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area is the area of the sides of a 3D shape, excluding the base(s), while total surface area includes the base(s) as well.
