To find the surface area of a rectangular prism, you need to calculate the total area of all six faces of the prism.
The formula for finding the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given dimensions:
l = 3m
w = 1.5m
h = 4m
Substitute the values into the formula:
Surface Area = 2(3)(1.5) + 2(3)(4) + 2(1.5)(4)
Surface Area = 6 + 24 + 12
Surface Area = 42 square meters
Therefore, the surface area of the rectangular prism is 42 square meters.
What is the surface area of the rectangular prism?
The numbers are: 3 m, 1.5 m, 4 m
