what is the surface area of a rectangular prism with the width 4cm lenth 5cm height of 3cm

2 answers

1. 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.

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.
