1. A cube’s volume is 512 cubic units. What is the length of its edge?

2. If a sphere fits snugly inside this cube, what is its volume?

3. What fraction of the cube is taken up by the sphere? What percentage is this? Explain or show your reasoning.

Sphere has radius 2 cm. Sphere has radius 4 cm.

1. Calculate the volume of each sphere.
2. The radius of Sphere is double that of Sphere . How many times greater is the volume of Sphere ?

Three cones have a volume of cm³. Cone has a radius of 2 cm. Cone has a radius of 3 cm. Cone has a radius of 4 cm. Find the height of each cone.

Match the description of each sphere to its correct volume.

While conducting an inventory in their bicycle shop, the owner noticed the number of bicycles is 2 fewer than 10 times the number of tricycles. They also know there are 410 wheels on all the bicycles and tricycles in the store. Write and solve a system of equations to find the number of bicycles in the store.
