Step 1: Write out the formula


\text{area of a rectangle = length }*\text{ width}

Step 2: Draw the net of the rectangular prism.

Step 3: Calculate the area of each rectangle


\text{Area of rectangle A = }5*3=15
\text{Area of rectangle B = }5*4=20
\text{Area of rectangle C = 3}*4=12
\text{Area of rectangle D = }5*4=20
\text{Area of rectangle E = }5*3=15
\text{Area of rectangle F = }4*3=12

Step 4: Add these values together


\text{the total surface area = }15+20+12+20+15+12=94\text{ square units}

the total surface area = 94 square units

1. Draw the net of the rectangular prism. 2. Calculate the area of each rectangle-example-1
