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.

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 cube?

Back

Surface Area = 6s², where s is the length of a side.

Front

What is the surface area of a cylinder?

Back

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

Front

What does 'L' represent in the surface area formulas for pyramids and cones?

Back

L represents the slant height.

Front

How do you find the surface area of a sphere?

Back

Surface Area = 4πr², where r is the radius.

Front

What is the surface area of a cone?

Back

Surface Area = πr(r + L), where r is the radius and L is the slant height.

Front

Calculate the surface area of a cube with a side length of 10 cm.

Back

Surface Area = 6(10 cm)² = 600 cm².

Front

If a cylinder has a radius of 3 cm and a height of 5 cm, what is its surface area?

Back

Surface Area = 2π(3 cm)(5 cm + 3 cm) = 48π cm².

Front

What is the surface area of a rectangular prism with dimensions 4 cm, 5 cm, and 6 cm?

Back

Surface Area = 2(4*5 + 4*6 + 5*6) = 2(20 + 24 + 30) = 2(74) = 148 cm².
