Someone please help me with the surface area
2 answers:
Surface are just means that you need to find the area of every face, then add.
TO find the Area of the rectangle do 16*8 = 128
For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28
There are four sides total and two triangles and two rectangles so 28+28+128+128= 312
SO the surface area is 312 in cubed
To find the Surface Area of a Triangular based prism you need to use the following formula: SA= bXh÷2 X H (of the prism)
In the question you have shown, the height is 8in, the base is 7in, and the height of the prism is 16in
so SA= 7X8÷2X16
= 448in^2
Therefore the Surface Area is 448in^2. Hope that helped!!
