To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then add them together.
Let's label the dimensions of the prism:
Length = 15
Width = 20
Height = 12
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Plugging in the values:
Surface Area = 2(15)(20) + 2(15)(12) + 2(20)(12)
Surface Area = 600 + 360 + 480
Surface Area = 1440
Therefore, the surface area of the right rectangular prism is 1440 square units.
What is the surface area of the right rectangular prism?
the numbers are, 15, 20, and 12.
