S A = 2 l w + 2 l h + 2 h w , where SA = surface area, l = length, w = width, and h = height. In the rectangular prism net above, l = 8 inches, w = 5 inches, and h = 3 inches. Simply put these numbers into the formula and solve for surface area.

Using the length and width you just measured, plug them into the formula to solve for the area. Multiply the length times the width to calculate area. For example, A = l x w = 5 x 2 = 10 cm2.

Multiply the perimeter of the base by the height of the prism to find the area of the lateral surface. Find the lateral surface area by multiplying the perimeter of the base by the height of the prism. Then add twice the area of the base.

The same is true for a square, but there's a key difference: For a square, the length and width are equal. If the length is L, then the area of the square is L2. If you know the area of the square, you can immediately calculate the length of each of its sides by rearranging the above equation: L = √A.

If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W. If you know the length and want the width, rearrange to get W = A ÷ L. Example: The area of a rectangle is 20 square meters, and its width is 3 meters.

Let's say the triangular prism has a length of 8 inches, a width of 8 inches, a height of 3 inches and a side length of 5 inches. Using the formula for surface area of a triangular prism, SA = wh + lw + lh + ls, we calculate a surface area of 152 square inches. Step 3: Subtract the overlapping parts from each figure.

The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W. If you know the length and want the width, rearrange to get W = A ÷ L.

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).
