## Math in Focus Grade 5 Chapter 15 Practice 2 Answer Key Drawing Cubes and Rectangular Prisms

**Draw on dot paper.**

Question 1.

Draw a unit cube.

Answer:

Explanation:

As a cube has all its sides of the same length.

A unit cube has all its sides of length 1 unit.

Shown the volume of a unit cube = Side × Side × Side,

= 1 unit × 1 unit × 1 unit,

= 1 unit cubes.

Question 2.

Draw two different views of a rectangular prism made up of 2 unit cubes.

Answer:

Explanation:

Drawn two different views of a rectangular prism made up of 2 unit cubes,

A unit cube has all its sides of length 1 unit

and 2 unit cubes shows the volume of a 2 unit cubes = 2 X (Sides × Side × Side),

= 2 X (1 unit × 1 unit × 1 unit),

= 2 unit cubes.

Question 3.

Draw two different solids made up of 3 unit cubes each.

Answer:

Explanation:

Drawn two different views of a rectangular prism made up of 3 unit cubes,

A unit cube has all its sides of length 1 unit

and 3 unit cubes shows the volume of a 3 unit cubes = 3 X (Sides × Side × Side),

= 3 X (1 unit × 1 unit × 1 unit),

= 3 unit cubes.

**Draw each cube or rectangular prism on the dot paper.**

**Example**
