**Distributorsolidsurface.com – **Understanding the surface area and volume of composite solids is an essential skill in geometry. Composite solids are three-dimensional figures that are formed by combining two or more basic shapes, such as cubes, cylinders, cones, and spheres. In this worksheet, we will explore various composite solids and practice calculating their surface area and volume. Grab a pencil and calculator, and let’s dive into the world of composite solids!

**Composite Solid 1: Cylinder on Top of a Cube**

Consider a composite solid consisting of a cylinder placed on top of a cube. The dimensions of the cube are as follows: length = 5 cm, width = 5 cm, and height = 5 cm. The dimensions of the cylinder are as follows: radius = 2 cm and height = 6 cm.

a) Calculate the total surface area of the composite solid. b) Determine the volume of the composite solid.

**Composite Solid 2: Cone Inside a Hemisphere**

Imagine a composite solid formed by placing a cone inside a hemisphere. The radius of the hemisphere is 4 cm, and the height of the cone is 6 cm. The radius of the cone’s base is 3 cm.

a) Find the surface area of the composite solid. b) Calculate the volume of the composite solid.

**Composite Solid 3: Cube with a Pyramid on Top**

Visualize a composite solid consisting of a cube with a pyramid on top. The cube has side length 6 cm, and the pyramid has a base side length of 4 cm and a height of 8 cm.

a) Determine the total surface area of the composite solid. b) Find the volume of the composite solid.

**Composite Solid 4: Sphere Surrounded by a Cylinder**

Consider a composite solid comprising a sphere surrounded by a cylinder. The radius of the sphere is 5 cm, and the height of the cylinder is 10 cm.

a) Calculate the total surface area of the composite solid. b) Determine the volume of the composite solid.

**Composite Solid 5: Cone on Top of a Hemisphere**

Imagine a composite solid formed by placing a cone on top of a hemisphere. The radius of the hemisphere is 6 cm, and the height of the cone is 8 cm. The radius of the cone’s base is 4 cm.

a) Find the surface area of the composite solid. b) Calculate the volume of the composite solid.
