There are 6 surface areas, but we need
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.

Well, if we want to find the surface area of a rectangular prism, we need to add up the areas of all its sides. So, let's get calculating!
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.Answer ID
