surface area =800
volume =80
the formula for the volume is: 1/3 • base •height= volume
the base is 16, and the height is 15. the final answer would be 80
there is no formula for the surface area. you must add the area of all the shapes together. to find the area of the triangle you need the slant height, which was not provided. to find the slant height you MUST do the pythagorean theorem.
8² + 15² = x², which will be 17. then to find the area of the triangle, you must do
base • height / 2. which will be 16•17/2, the answer is 136. now the square, you must do base •height. which will be 16•16, and the answer would be 256. now add the area of the triangles and the square.
136+136+136+136+256=800
