to calculate only 3 because:
The Front and Back are equal.
The Left and Right are equal.
The Top and Bottom are equal.
So we multiply each calculation by 2:
As = 2(4*3) + 2(5*3) + 2(4*5),
As = 24 + 30 + 40 = 94cm^2.

The formula for finding the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
In this case, the width (w) is 4 cm, the length (l) is 5 cm, and the height (h) is 3 cm. So let's plug in those values:
Surface Area = 2(4)(5) + 2(4)(3) + 2(5)(3)
Now, let's calculate this mathematically:
Surface Area = 40 + 24 + 30
Adding it all up, we get:
Surface Area = 94 cm²
So, the surface area of the rectangular prism with a width of 4 cm, a length of 5 cm, and a height of 3 cm is 94 cm².

Given the dimensions of the rectangular prism:
Width = 4 cm
Length = 5 cm
Height = 3 cm
Using the formula, we can plug in these values:
Surface Area = 2(4)(5) + 2(4)(3) + 2(5)(3)
Simplifying the equation:
Surface Area = 40 + 24 + 30
Surface Area = 94
Therefore, the surface area of the rectangular prism is 94 square centimeters.

A rectangular prism has six faces:
1. The top and bottom faces are both rectangles with dimensions length x width.
2. The front and back faces are both rectangles with dimensions height x width.
3. The left and right faces are both rectangles with dimensions height x length.
Given the dimensions:
- Width = 4 cm
- Length = 5 cm
- Height = 3 cm
The formula to calculate the surface area of a rectangular prism is:
Surface Area = 2(length x width) + 2(width x height) + 2(height x length)
Substituting the given values into the formula, we get:
Surface Area = 2(5 x 4) + 2(4 x 3) + 2(3 x 5)
Surface Area = 2(20) + 2(12) + 2(15)
Surface Area = 40 + 24 + 30
Surface Area = 94 cm²
Therefore, the surface area of the rectangular prism with a width of 4 cm, length of 5 cm, and height of 3 cm is 94 cm².
