A cylinder and a sphere.

Question 6.

Answer:

Explanation:

In this composite shape we have used

A rectangular prism and 2 cubes

**Circle the shape that is not used to make the composite shape shown.**

Question 7.

Answer:

Explanation:

In this composite shape we have used

a sphere and a cone.

**Problem Solving**

Question 8.

How many faces are there in all on the composite shape shown?

______________ faces

Answer:

7 faces

Explanation:

A cone has one face and a cube has 6 faces

1 + 6 = 7

so, the composite shape has 7 faces.

Question 9.

Circle the shapes that have two or more faces.

Answer:

Explanation:

A cylinder has 2 faces

cube and rectangular prism has 6 faces each.

Question 6.

How many faces do a cube and cylinder have in all?

(A) 2

(B) 4

(C) 6

(D) 8

Answer:

8 faces

Explanation:

A cube has 6 face and a cylinder has 2 faces
