Composite Surface Area Practice

Front

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

Back

The surface area of a cube is given by the formula: SA = 6a², where 'a' is the length of a side.

Front

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

Back

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

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

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

Back

To find the surface area of a composite figure, calculate the surface area of each individual shape and then sum them up.

Front

What is the surface area of a square pyramid?

Back

The surface area of a square pyramid is given by the formula: SA = b² + 2bs, where 'b' is the base length and 's' is the slant height.

Front

What is the total surface area of two cubes with side length 10 cm?

Back

The total surface area is 2 * (6 * 10²) = 1200 cm².

Front

If a right prism has a base area of 50 cm² and a height of 10 cm, what is its surface area?

Back

The surface area is SA = 2 * base area + perimeter of base * height = 2 * 50 + (perimeter of base * 10).

Front

What is the perimeter of a rectangle with length 8 cm and width 5 cm?

Back

The perimeter is P = 2(l + w) = 2(8 + 5) = 26 cm.

Front

How do you calculate the lateral surface area of a right prism?

Back

The lateral surface area is calculated as the perimeter of the base multiplied by the height of the prism.

Front

What is the surface area of a cylinder with radius 3 cm and height 5 cm?

Back

The surface area is SA = 2πr(h + r) = 2π(3)(5 + 3) = 48π cm².
