Surface Area

Front

What is Surface Area?

Back

The total area of the surface of a three-dimensional object.

Front

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

Back

Add the areas of all six faces: SA = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is a Net in geometry?

Back

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

Front

What 3D solid does this net create? (Image of a net for a square pyramid)

Back

Square Pyramid.

Front

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

Back

96 cm² (SA = 6s², where s = side length).

Front

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

Back

SA = 2πr(h + r), where r = radius and h = height.

Front

What is the surface area of a triangular prism?

Back

SA = bh + (perimeter of base) * height, where b = base area.

Front

What do we call the three-dimensional shape with a circular base and a single vertex?

Back

Cone.

Front

What is the surface area of a sphere?

Back

SA = 4πr², where r = radius.

Front

What is the difference between area and surface area?

Back

Area refers to the size of a 2D shape, while surface area refers to the total area of a 3D object's surface.
