Flashcard 4-1 Surface Area

Front

What is the name of this 3D solid?

Back

Cylinder

Front

Name the figure: A solid with two parallel bases that are congruent rectangles.

Back

Rectangular Prism

Front

Name the figure: A solid with a triangular base and three triangular faces that meet at a point.

Back

Triangular Pyramid

Front

What is the total surface area of a square pyramid?

Back

The total surface area is calculated using the formula: SA = Base Area + Lateral Area. For a square pyramid, SA = s^2 + 2 * s * l, where s is the side length of the base and l is the slant height.

Front

For a sphere with a radius of 8, what is the Surface Area?

Back

The surface area of a sphere is calculated using the formula: SA = 4πr². For r = 8, SA = 4π(8)² = 803.84 square units.

Front

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

Back

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

Front

What is the name of a solid with a circular base and a single vertex?

Back

Cone

Front

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

Back

SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the total surface area of a triangular prism?

Back

SA = (Base Area) + (Lateral Area). The lateral area is the perimeter of the base times the height.

Front

What is the formula for the surface area of a square pyramid?

Back

SA = s² + 2 * s * l, where s is the side length of the base and l is the slant height.
