a rectangular prism is 12 inchs wide 3 inchs high and 5 inchs long,
Solve for the surface area of the rectangular prism.
The surface area of a rectangular prism can be found by adding the areas of all six sides.
The formula for finding the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given:
l = 12 inches
w = 3 inches
h = 5 inches
Substitute the values into the formula:
Surface Area = 2(12)(3) + 2(12)(5) + 2(3)(5)
Surface Area = 72 + 120 + 30
Surface Area = 222 square inches
Therefore, the surface area of the rectangular prism is 222 square inches.
