#3 Volume and Surface area Composite Solids

Front

What is a composite solid?

Back

A composite solid is a three-dimensional shape that is made up of two or more simple geometric shapes, such as prisms, cylinders, cones, and pyramids.

Front

How do you calculate the volume of a prism?

Back

The volume of a prism is calculated using the formula: Volume = Base Area × Height.

Front

What is the formula for the volume of a pyramid?

Back

The volume of a pyramid is calculated using the formula: Volume = (1/3) × Base Area × Height.

Front

What is the formula for the volume of a cone?

Back

The volume of a cone is calculated using the formula: Volume = (1/3) × π × r² × h, where r is the radius and h is the height.

Front

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

Back

To find the surface area of a composite solid, calculate the surface area of each individual shape and then sum them up, subtracting any overlapping areas.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area that the surface of an object occupies, while volume measures the amount of space an object occupies.

How do you calculate the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula: Volume = π × r² × h, where r is the radius and h is the height.

Front

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

Back

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

Front

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

Back

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

How do you find the radius from the diameter?

Back

The radius is found by dividing the diameter by 2: Radius = Diameter / 2.
