Last one help. Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole

Fed [463]

The formula for finding the lateral area for a triangular prism is
$A_{L} = (a + b + c )h$

So put in the values and you get

$A_{L} = (12.04 + 9 + 8 )23$
$A_{L} = 668$

The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H

So put in all the values and you get

SA = 9(8) + (9 + 8 + 12.04)23
SA = 740

Hope this helps! :)
