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 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 + (s1 + s2 + s3)h, where b is the base area, s1, s2, s3 are the lengths of the triangular sides, and h is the height.

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 do you calculate the surface area of a pyramid?

Back

The surface area of a pyramid is calculated using the formula: SA = Base Area + (1/2 * Perimeter * Slant Height).

Front

What is the surface area of a cube?

Back

The surface area of a cube is calculated using the formula: SA = 6a², where a is the length of a side.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a solid, while volume measures the amount of space inside the solid.

Front

What is the surface area of a triangular prism with a base area of 12 m² and a height of 10 m?

Back

The surface area is calculated using the formula: SA = 12 + (perimeter of base * height).

Front

What is the surface area of a rectangular prism with dimensions 3 cm, 4 cm, and 5 cm?

Back

The surface area is 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 cm².
