Find the surface area of the rectangular prizm
the prism has three pairs of rectangular faces. I'm sure you know how to find the area of a rectangle...
As = (W*h)*2 + (L*W)*2 + (L*h)*2.
To find the surface area of a rectangular prism, you need to calculate the area of each individual face and then add them up.
A rectangular prism has six faces - a top and bottom face that are identical, and four side faces. The top and bottom faces are both rectangles, and the side faces are also rectangles.
To find the area of a rectangle, you multiply its length by its width.
So, let's assume that the length of the rectangular prism is L, the width is W, and the height is H.
To find the area of the top and bottom faces, which are rectangles, you multiply the length by the width:
Area of top and bottom faces = L * W * 2
Since there are two identical top and bottom faces, we multiply by 2.
To find the area of the side faces, which are also rectangles, you multiply the height by the width:
Area of side faces = H * W * 2
Again, since there are four identical side faces, we multiply by 2.
Finally, to find the surface area of the rectangular prism, you add up the area of all the faces:
Surface area = (Area of top and bottom faces) + (Area of side faces)
Surface area = (L * W * 2) + (H * W * 2)
Simplifying, we get:
Surface area = 2(LW + HW + HW)
So, to find the surface area of a rectangular prism, you need to know the lengths of its sides and apply the formula 2(LW + HW + HW).
