Finding the surface area of a rectangular prism

The video tutorial explains how to calculate the surface area of a rectangular prism. It begins by identifying the six sides of the prism and highlights the symmetry between opposite sides. The tutorial then provides a step-by-step guide to calculating the surface area by multiplying the area of one side by two for each pair of opposite sides. The video concludes with tips on simplifying calculations by using symmetry and multiplication, ensuring all sides are accounted for.

What is the first step in finding the surface area of a rectangular prism?

• Find the perimeter of the base

• Measure the height of the prism

• Identify and calculate the area of each face

• Calculate the volume of the prism

How can the calculation of surface area be simplified for a rectangular prism?

• By ignoring the top and bottom faces

• By calculating the area of one face and multiplying by six

• By using the symmetry of opposite faces and multiplying by two

• By only calculating the area of the front face

What is the area of the front and back faces if the dimensions are 15 by 9?

• 135
