The base of a triangular prism is a right triangle whose legs are 7 cm and 24 cm. The height of the prism is 30 cm. What is the lateral area of the prism?
ok, base area: triangle sides are 25cm each, or .25m s=semiperimeter area=s(sqrt(s-side)^3) s=75/2 s-side=37.5-25=12.5 area=37.5*12.5*sqrt12.5 let E6 mean 10^6 .075E6m=1/3 (37.5*12.5*(sqrt12.5))h solve for h I get:137cm I hope that helped
