Best ResponseYou've already chosen the best response.2volume is the product of those 3 values, and the same for the other rectangular prism, now with the triangular prism just remember that \[A=\frac{1}{2}*base*height\]

Best ResponseYou've already chosen the best response.1so, length∗width∗height A=1\2∗base∗height

Best ResponseYou've already chosen the best response.2and because you are multiplying values with "inches" as the units, the volume is in inches cubed, \[in^3\]

Best ResponseYou've already chosen the best response.17*7*8 = 392 7*7*8 = 392 8*7/2=28 so 392+392+28=812in3
