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

Back

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

Front

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

Back

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

Front

What is the surface area of a square pyramid?

Back

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

Front

What is the total surface area of a cylinder?

Back

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

Front

How do you calculate 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 cube?

Back

Surface Area = 6a², where a = length of a side.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.

Front

If a rectangular prism has dimensions 3m, 4m, and 5m, what is its surface area?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 m².

Front

What is the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

How do you find the surface area of a composite shape?

Back

Calculate the surface area of each individual shape and then sum them up.
