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

The Surface Area (SA) of a rectangular prism is calculated using the formula: SA = 2(lw + lh + wh), where l = length, w = width, and h = height.

Front

What is the Surface Area of a cube with side length 4 cm?

Back

The Surface Area of a cube is calculated using the formula: SA = 6s². For a cube with side length 4 cm, SA = 6(4)² = 96 cm².

What is the formula for the Surface Area of a cylinder?

Back

The Surface Area (SA) of a cylinder is calculated using the formula: SA = 2πr(h + r), where r = radius and h = height.

Front

If a rectangular prism has a length of 10 cm, width of 5 cm, and height of 2 cm, what is its Surface Area?

Back

SA = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 cm².

Front

What is the Surface Area of a sphere with a radius of 3 cm?

Back

The Surface Area (SA) of a sphere is calculated using the formula: SA = 4πr². For a sphere with radius 3 cm, SA = 4π(3)² = 36π ≈ 113.1 cm².

Front

What is the Surface Area of a triangular prism?

Back

The Surface Area of a triangular prism is calculated using the formula: SA = bh + (perimeter of base * height), where b = base area and h = height of the prism.

Front

How do you find the Surface Area of a cone?

Back

The Surface Area (SA) of a cone is calculated using the formula: SA = πr(r + l), where r = radius and l = slant height.

Front

What is the Surface Area of a rectangular brick with dimensions 5 cm x 9 cm x 20 cm?

Back

SA = 2(5*9 + 5*20 + 9*20) = 2(45 + 100 + 180) = 2(325) = 650 cm².

Front

What is the total Surface Area of a cube with a side length of 6 cm?

Back

SA = 6s² = 6(6)² = 6(36) = 216 cm².
