Surface Area

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

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.

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

A cube has 6 faces.

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.

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.

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.

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

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

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.
