The post What is the surface area of this triangular prism? appeared first on homeworkcrew. If you have any questions please do not hesitate to leave a comment! To find the surface area add all the areas up: Therefore #length times width = 5 in times 2 in = color(green)(10 in^2)# Plug the decimal dimensions in SA bh + (s1 + s2 + s3)H, where ‘b’ and ‘h’ are the base length and height of the triangle ‘s1’, ‘s2’, and ‘s3’ are the lengths of three sides of the triangle ‘H’ the prism's height, and find the surface area. This side is also a rectangle with length of #5 in# and a width of #2 in#. Surface Area of Triangular Prisms Decimals. It is expressed in square units such as m 2, cm 2, mm 2, and in 2. Therefore #length times width = 2 in times 3 in = color(pink)(6 in^2)# The surface area of a triangular prism is the entire space occupied by its outermost layers (or faces). This side of the prism (outlined in pink) is also a rectangle with a width of #3 in# and length of #2 in# (since the blue-circled sides are parallel and the prism structure is perpendicular). Therefore #length times width = 4 in times 2 in = color(orange)(8 in^2)# Complete each step using the formula surface area equals two times b plus p times h to find the surface area of the triangular prism. The formula to calculate the area of the triangle is #length times width# and the rectangle at the bottom has base of #4 in# and width of #2 in#. The bottom of the prism is a rectangle since the angles are 90 degrees. There are two triangular surfaces (one in yellow and white) so multiply the area of the triangle by factor of #2#: #6 in^2 times 2 = color(blue)(12 in^2)# Using the area formula for triangles (#1/2bh# where #b# is the base and #h# is the height) the area of the triangular surface is #1/2bh=1/2(3 in)(4 in) = 1/2 (12 in^2)=6 in^2#. This triangular surface is 3 inches (height) by 4 inches (base). Let’s calculate each side separately and then we can add them up at the end. The surface area of that prism is basically all the areas that you can touch (total area of the outside/surface). In extremely simple terms imagine you have a woodblock shaped like the triangular prism in picture you attached. Even though the explanation might seem slightly long it is really easily broken down into pieces so I highly recommend you read and learn from it. The surface area of this prism is #36 in^2#.
