Surface Area of Nets

Front

What is surface area?

Back

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

Front

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

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

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

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height).

Front

What is a net in geometry?

Back

A net is a two-dimensional pattern that can be folded to form a three-dimensional figure.

Front

How do you find the surface area of a triangular pyramid?

Back

Surface Area = Base Area + (1/2 x Perimeter of Base x Slant Height).

Front

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

Back

Surface Area = 6s² = 6(4 cm)² = 96 cm².

Front

If a triangular prism has a base area of 30 cm² and a height of 10 cm, what is the surface area?

Back

Surface Area = (30 cm² x 2) + (Perimeter of Base x 10 cm).

Front

What is the surface area of a cylinder with radius 3 cm and height 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(5 + 3) = 48π cm².

Front

How do you find the area of a triangle?

Back

Area = (1/2) x base x height.

Front

What is the surface area of a sphere with a radius of 5 cm?

Back

Surface Area = 4πr² = 4π(5 cm)² = 100π cm².
