Surface Area Rectangular Prisms

How do you find the surface area of a 3 dimensional object?

• Divide the area of the base by 2 and multiply by the height.
• Divide the sum of the bases and multiply by the height.
• Multiply all faces together. 
• Find the sum of all of the areas of all of the faces or find the sum of the front, back and top and multiply by 2.
