Answer:
1. 76017.69 mm^2 or 76.02 m^2
2. 631332.52 mm^3 or 631.33 m^3
Step-by-step explanation:
1. The equation for the surface area of an equilateral trianglula prism is
2 * ( ( sqrt(3) / 4 ) * s^2) + 3( h * s )
2 * ( ( sqrt(3) / 4 ) * 60^2) + 3( 405 * 60 )
76017.69 mm^2 or 76.02 m^2
2. The equation for the volume of an equilateral trianglula prism is
( sqrt(3) / 4 ) * s^2 * h
( sqrt(3) / 4 ) * 60^2 *405
631332.52 mm^3 or 631.33 m^3
