Am confused. The bases of a prism are right triangles with side lengths 6 meters, 8 meters, and 10 meters. The height of the prism is 3 meters. What is the lateral area of the prism? What is the total surface area?
L=Ph perimeter is side(1) +side(2)+side(3)
6+8+10=24 (3)=72m^2
I know s.a. is 2B+bh....but I don't know the B; which is B=1/2bh. What is the base, so I can put in formula?
