# Unit 11 Volume and Surface Area Homework 7 Answer Key

When it comes to completing unit 11 volume and surface area homework, having an answer key on hand can be a great help. Not only does it help you check your answers, but it can also give you an idea of how to approach your work. With this in mind, here is the answer key for unit 11 volume and surface area homework 7.

## Part 1: Volume of a Right Rectangular Prism

The volume of a right rectangular prism can be calculated by multiplying its length, width, and height. The answer for this particular question is 12,000 cm3. To arrive at this answer, we need to multiply the length (15 cm), width (20 cm), and height (8 cm) of the right rectangular prism.

## Part 2: Volume of a Cylinder

The volume of a cylinder can be calculated by multiplying the radius squared by the height and pi. The answer for this particular question is 15,707 cm3. To arrive at this answer, we need to first determine the radius (15 cm) and then multiply this by the height (13 cm) and pi (3.14).

## Part 3: Volume of a Cone

The volume of a cone can be calculated by multiplying the radius squared by the height, one-third, and pi. The answer for this particular question is 15,707 cm3. To arrive at this answer, we need to first determine the radius (15 cm) and then multiply this by the height (13 cm), one-third (1/3), and pi (3.14).

## Part 4: Surface Area of a Right Rectangular Prism

The surface area of a right rectangular prism can be calculated by multiplying its length, width, and height twice and then adding the four sides together. The answer for this particular question is 1,848 cm2. To arrive at this answer, we need to first multiply the length (15 cm), width (20 cm), and height (8 cm) twice and then add the four sides together.

## Part 5: Surface Area of a Cylinder

The surface area of a cylinder can be calculated by multiplying the circumference by the height and then adding the two bases together. The answer for this particular question is 1,159 cm2. To arrive at this answer, we need to first determine the circumference (94.24 cm) and then multiply this by the height (13 cm). Then we need to add the two bases together.
