Lesson: Surface Areas of Rectangular Prism and Cubes Mathematics • 6th Grade

In this lesson, we will learn how to calculate surface areas of rectangular prisms and cubes and use this to solve real-life problems.

Lesson Plan

Students will be able to

define the lateral and total surface areas,
calculate the lateral surface area using the sum of 4 faces,
calculate the surface area using the sum of the area of the faces and the two bases,
calculate the lateral surface area using the perimeter of ,
solve problems involving surface area.

Q1:

If the perimeter of the base of a cube is 54.4 cm, find its total surface area.

Q2:

What is the surface area of a cube of side 17 centimeters?

Q3:

Find the surface area of a cube of length 11 centimeters.
