Surface AREA (3/21)

Front

What is Surface Area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies. It is measured in square units.

Front

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

Back

The surface area of a rectangular prism can be calculated using the formula: SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the unit of measurement for surface area?

Back

The unit of measurement for surface area is square units, such as cm², m², or ft².

Front

What is the surface area of a cube with a side length of 3 cm?

Back

The surface area of a cube is calculated using the formula: SA = 6s². For a cube with side length 3 cm, SA = 6(3)² = 54 cm².

Front

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

Back

The surface area of a cylinder is calculated using 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, use the formula: SA = bh + (perimeter of base) * height, where b is the base area.

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 surface area and volume?

Back

Surface area measures the total area of an object's surface, while volume measures the amount of space an object occupies.

Front

If a rectangular prism has dimensions 4 cm, 5 cm, and 6 cm, what is its surface area?

Back

SA = 2(4*5 + 4*6 + 5*6) = 2(20 + 24 + 30) = 2(74) = 148 cm².

Front

What is the surface area of a cone?

Back

The surface area of a cone is calculated using the formula: SA = πr(r + l), where r is the radius and l is the slant height.
