Surface Area

Front

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

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

Front

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

Back

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

Front

How do you find the surface area of a cone?

Back

Surface Area = πr(r + l), where r = radius and l = slant height.

Front

What is the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

If a cube has a side length of 3 cm, what is its surface area?

Back

Surface Area = 6s² = 6(3)² = 54 cm².

Front

What is the relationship between surface area and volume?

Back

Surface area measures the extent of an object's surface, while volume measures the space it occupies. Increasing surface area can affect heat transfer and chemical reactions.

Front

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

Back

Surface Area = bh + (perimeter of base) * height, where b = base, h = height of the prism.

Front

What is the surface area of a cylinder with a radius of 4 in and a height of 10 in?

Back

Surface Area = 2π(4)(10) + 2π(4)² = 80π + 32π = 112π in².

How do you find the surface area of a rectangular brick?

Back

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