Surface Area

Front

What is surface area?

Back

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

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

Back

To calculate 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 shape that can be folded to form the shape.

Front

How many faces does a cube have?

Back

A cube has 6 faces.

Front

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

Back

The surface area of a cube is calculated using the formula: SA = 6s². For a side length of 4 cm, SA = 6(4)² = 96 cm².

Front

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

Back

To find the surface area of a triangular prism, calculate the area of the two triangular bases and the three rectangular sides, then sum them up.

Front

What is the relationship between surface area and volume?

Back

Surface area measures the total area of the surface, while volume measures the space inside the object. They are related but represent different properties.

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

How do you determine the surface area of a composite shape?

Back

To determine the surface area of a composite shape, break it down into simpler shapes, calculate the surface area of each, and then sum them up.
