The bottom has the same area, so the area of the two together is 2 times 30 = 60. Surface Area Calculate the surface area of the rectangular. The top has a length of 6 and a width of 5, so its area is 6 X 5 = 30. Surface Area The formula for the surface area of a rectangular prism is 2(lw) + 2(wh) + 2(lh).Surface Area Sum of areas of all six faces. The area of the two together is 2 times 24 = 48. Here is the basic idea to find surface area of the above rectangular prism. (In the diagram, you can’t see the side on the left.) Each of those sides measures 6 x 4, so each one’s area is 24. Now consider the sides on the left and right.There is an identical piece in the back with the same area the area of the two together is 2 times 20 = 40. Let’s start with the side that stares you in the face on the diagram.Step 2: Draw a net diagram using the given side length. This box has six sides, three pairs of congruent sides. Surface Area 366 in 13 in 9 in 3 in 2) Surface Area 448 yd 20 yd 6 yd d Surface Area 750 ft 4) Surface Area 724 yd 6) Surface Area 390 in Printable Worksheets Name : Answer key Surface Area - Rectangluar Prism d d d 13 ft 19 ft t 14 in 9 in 3 in 12 ft t 7 ft 8 yd 15 yd d 5) Find the surface area of. Step 1: Identify the given side lengths of a rectangular prism. Calculate the Surface Area of a Rectangular Prism Worksheet. The area of each side is length times width. Lets build our equation for surface area of a rectangular prism starting with our formula: A 2 (wl + lh + hw) A 2 w l + l h + h w. Surface Area of a Rectangular Prism Worksheets. It’s your typical box.Ī right rectangular prism’s surface area is the sum of the areas of all its faces: the top, the bottom, and the four sides. Solution Sidebar: Surface Area of a Right Rectangular PrismĪ right rectangular prism is the shape of a box with a rectangle for a bottom, with sides perpendicular to its bottom, and with a flat top parallel to its bottom.
