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.

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.

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

Back

The surface area is 96 cm², calculated using the formula SA = 6s², where s is the side length.

How do you find 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

What is the surface area of a triangular prism?

Back

The surface area of a triangular prism is calculated by adding the areas of the two triangular bases and the three rectangular sides.

Front

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

Back

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

How do you calculate the area of a composite figure?

Back

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

What is the surface area of a hexagonal prism?

Back

The surface area of a hexagonal prism can be calculated using the formula: SA = 2(Area of hexagon) + (Perimeter of hexagon × height).
