Composite Solids Surface Area & Volume Practice

Front

What is a composite solid?

Back

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

Front

How do you find the volume of a composite solid?

Back

To find the volume of a composite solid, calculate the volume of each individual shape and then add them together.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

Front

What is the formula for the volume of a sphere?

Back

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius.

Front

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

Back

The surface area of a cylinder is given by the formula SA = 2πr(h + r), where r is the radius and h is the height.

Front

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

Back

The surface area of a sphere is given by the formula SA = 4πr², where r is the radius.

Front

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

Back

To calculate the surface area of a composite solid, find the surface area of each individual shape and then add them together, making sure to account for any overlapping areas.

Front

What is the importance of rounding in volume calculations?

Back

Rounding is important in volume calculations to provide a simpler, more understandable number, especially when dealing with real-world measurements.

Front

What units are used for measuring volume?

Back

Common units for measuring volume include cubic centimeters (cm³), cubic meters (m³), and cubic feet (ft³).
